1. INTRODUCTION
The P5E GNSS Reference Receiver User Guide describes how to set up and
use the CHC® P5E™ GNSS reference receiver.
In this manual, “the receiver” refers to the P5E GNSS reference receiver
unless otherwise stated.
Even if you have used other Global Navigation Satellite Systems (GNSS)
products before, CHC recommends that you spend some time reading this
manual to learn about the special features of this product. If you are not
familiar with GNSS, go to www.chcnav.com for an interactive look at CHC
and GNSS.
1.1. ABOUT THE RECEIVER
The P5E GNSS reference receiver (“the receiver”) is a multiple-frequency
GNSS receiver. It can track all GPS (L1/L2/L5), GLONASS (L1/L2), BDS (B1/B2)
and GALILEO(E1/E2/E5)signals.
You can use the front panel of the receiver or an office computer to
configure the receiver, access files, and publish data files to a company
Intranet or to the Internet. The receiver makes it easy for you to set up a
powerful, flexible, and reliable reference station for continuous operation.
The receiver serves in all common geodetic reference receiver roles. It can
be the main component in a Continuously Operating Reference Station
(CORS), streaming data to CHC GNSS Infrastructure software. It can also work
well as a campaign receiver prior to permanent deployment. The receiver
makes an excellent portable RTK base station with its internal battery. It also
has specialized capabilities that make it an excellent reference receiver for
scientific applications.

2. OVERVIEW
This chapter introduces the P5E GNSS reference receiver (“the receiver”).
This receiver makes it easy to set up a powerful and reliable Continuously
Operating Reference Station (CORS) or to collect data from temporary field
locations.
The receiver is ideal for the following infrastructure applications:
•
As part of a GNSS Infrastructure network in conjunction with CHC
Reference Station Network (CPS) software.
•
As part of a permanent reference station with or without supporting
software.
•
A temporary field base station to broadcast RTK corrections and collect
observations for post processing.
2.1. RECEIVER FRAMEWORK
The receiver integrates the multi-frequency GNSS technology into a
specialized processing and communications framework. The receiver can
operate as a standalone reference station or it can be integrated into a
scalable network.
With an Internet Protocol (IP) as the primary communications method, you
can use public domain tools, such as a web browser and FTP client, to
configure the receiver and access logged data files.
NOTE - All references to the Internet refer to either a Wide Area
Network (WAN) or a Local Area Network (LAN) connection.
The receiver adopts a secured system that requires a password protected
login for configuration changes and/or file access.
Use the network management features to create a base/rover configuration
with a variety of operating modes. You can then enable those modes as
necessary instead of switching the global state of the receiver from one
mode to another. For example, you can configure a number of streaming
services with different configurations (such as any combination of data
stream, sample interval) on different TCP or UDP ports. To activate one or
more modes, open the connection to the specific port. This allows multiple
clients to access any given streaming service.
These features and many more, shift the model of a GNSS receiver toward
the concept of a "network appliance".
P5E GNSS Reference Receiver User Guide

2. Overview
2.1.1. THE NETWORK APPLIANCE CONCEPT
Traditionally, a GNSS receiver has one operator. That person is the only user
of the receiver so they can change settings without affecting other users.
With the P5E GNSS reference receiver, an operator can configure a receiver
once, and then make it available as a network appliance for general use by
one or more users (or clients).
This network appliance concept lets you set up the receiver to provide one
or more services that one or more users can access through a Local Area
Network (LAN) or a Wide Area Network (WAN), such as the Internet. Once
the receiver is set up, you need make only minimal changes, if any, to the
receiver configuration.
When the receiver is operating as a network appliance, it provides services
to all users attached to the receiver through the network.
Different streamed services may be configured on different ports, for
example, with differing data rates or data combination. To obtain a service,
the client has only to connect to a specific port. In this way, most users do
not need to control the receiver. Changing global settings, such as masks, will
affect all users of all services.
The receiver provides the following standard configuration and data logging
services:

HTTP
All manual and automated configuration operations to manage
the logged data file space.
Remote manual and/or automated operations to manage the
logged data file upload path.

2.2. RECEIVER SERVICES
The receiver can provide one or more streaming or query services over a
RS-232 serial port or a TCP/IP port:
•
Streaming service
Anyone with authorized access can obtain streamed information, such
as GNSS measurements or RTCM corrections, without having to control
or issue commands to the receiver. The client simply connects to the
port that is streaming the required information.

2.4. USE AND CARE
This receiver can withstand the rough treatment and tough environment
that typically occurs in CORS installation. However, it is a high-precision
electronic instrument and should be treated with reasonable care.
CAUTION – Operating or storing the receiver outside the specified
temperature range can damage it. For more information, see Chapter 8
Specifications.
2.5. ELECTRONIC INTERFACE
High-power signals from a nearby radio or radar transmitter can overwhelm
the receiver circuits. This does not harm the instrument, but it can prevent
the receiver electronics from functioning correctly.

3. BATTERIES AND POWER
The P5E GNSS reference receiver uses an internal rechargeable Lithium-ion
battery, which can be replaced only at an Authorized CHC Service Center.
The receiver can also be powered by an external power source that is
connected to either of the Lemo ports.
The operational time provided by the internal battery depends on the type
of measurement and operating conditions. Typically, the internal battery
provides up to 24 hours operation.
NOTE–All battery operational tests are carried out with new,
fully-charged batteries at room temperature, tracking both GPS and
GLONASS satellites while storing and streaming data at 1 Hz. Older
batteries, at temperatures significantly higher or lower than room
temperature, will have a reduced performance. Power consumption
increases with an increasing number of actively tracked satellites and
with increasing observation and storage rates.
3.1. EXTERNAL POWER
The receiver uses an external power source in preference to its internal
battery. If the receiver is not connected to an external power source, or if
the external power supply fails, the internal battery is used.
CHC recommends that the applied external power offers between 9 V DC
and 36 V DC and is able to supply at least 6.5 W of power for the long-term
installations and ensuring that the internal battery is charged and ready to
compensate for power supply disruptions.
While carrying out static measurements for post-processed computations
using the internal memory, if no external power is supplied and the internal
battery is drained, the receiver shuts down. No data is lost; however, when
power is restored, the receiver should be configured again.
WARNING – The external AC power adapter and its associated power cord
and plug are not intended to be installed outdoors, nor in a wet location. Do
not power the receiver through external power when operating in a wet
environment or an environment that may become wet. The power input
connections must be sheltered.
WARNING – When you apply DC voltage to this product through the Lemo
connector, the DC voltage must be limited to 36V DC +0% under both
normal and single fault conditions. This product may present an electrical

hazard if the recommended input voltage is exceeded.
3.2. BATTERY SAFETY
The receiver is powered by a rechargeable internal Lithium-ion battery.
Charge and use the battery only in strict accordance with the following
instructions.
WARNING – Do not damage the rechargeable Lithium-ion battery. A
damaged battery can cause an explosion or fire, and can result in personal
injury and/or property damage.
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of
damage include, but are not limited to, discoloration, warping, and
leaking battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.
WARNING – Avoid contact with the rechargeable Lithium-ion battery if it
appears to be leaking. Battery fluid is corrosive, and contact with it can
result in personal injury and/or property damage.
To prevent injury or damage:
– If the battery leaks, avoid contact with the battery fluid.
– If battery fluid gets into your eyes, immediately rinse your eyes with
clean water and seek medical attention. Do not rub your eyes!
– If battery fluid gets onto your skin or clothing, immediately use clean
water to wash off the battery fluid.
3.3. BATTERY PERFORMANCE
To optimize battery performance and extend battery life:
•
Fully charge all new batteries before use.
•
Do not use at extreme temperatures. The receiver is designed to
operate at -40 °C to +65 °C (-40 °F to +149 °F). However, operation at
temperatures of less than 0 °C (32 °F) can cause a rapid drop in battery
life.

3. Batteries and Power
3.4. CHARGING THE BATTERY
The rechargeable Lithium-ion battery is supplied partially charged. Charge
the battery completely before using it for the first time. If the battery has
been stored for longer than three months, charge it before use.
When connected to a suitable power source, the internal battery charges
fully in 10 hours.
WARNING – Charge and use the rechargeable Lithium-ion battery only in
strict accordance with the instructions. Charging or using the battery in
unauthorized equipment can cause an explosion or fire, and can result in
personal injury and/or equipment damage.
To prevent injury or damage:
– Do not charge or use the battery if it appears to be damaged or leaking.
– Charge the Lithium-ion battery only within the P5E receiver. The battery
can only be removed by an authorized CHC Service Center.
3.5. STORING THE BATTERY
The internal Lithium-ion battery adopts a self-protection mechanism that
protects the battery from discharge when its voltage is below 6 V and shuts
down the receiver. The internal battery will be activated when charged by
the external power supply.
Do not store the receiver at temperatures outside the range -40°C to +85 °C
(-40°F to 176°F).
The receiver is supplied with a mains power supply unit that recharges the
battery inside the receiver when it is connected through the adaptor to
either of the Lemo ports. When you use the receiver in a long-term
installation, CHC recommends that you use this power supply or another
that provides at least 9 V DC at all times to keep the internal battery charged.
This will ensure that the internal battery provides an uninterrupted power
supply that will keep the receiver operational for up to 24 hours after a
power failure.
3.6. REMOVING THE BATTERY
The internal Lithium-ion battery may be removed only at an authorized CHC
Service Center. If the battery is removed at an unauthorized service center,
the remaining warranty on the product will be void.

4. SETTING UP THE RECEIVER
This chapter describes best practices for setting up the equipment, and
outlines the precautions that you must take to protect the equipment. It also
describes the typical installation diagram of reference station composed of
P5E GNSS receiver, GNSS antenna, external power and network cable.
The antenna installation guidelines described here are the minimum
standards. When installing a geodetic antenna to gather precise observation
data, always follow recommended CORS installation practices to the greatest
extent possible.
4.1. GUIDELINES
When you set up the receiver, follow these guidelines.
4.1.1. ENVIRONMENTAL CONDITIONS
The receiver has a waterproof housing but you must take reasonable care to

To improve the performance and long-term reliability of the receiver, do not
expose the receiver to extreme environmental conditions, such as:
•
Water
•
Heat greater than 65 °C (149 °F)
•
Cold less than -40 °C (-40 °F)
•
Corrosive fluids and gases
4.1.2. SOURCES OF ELECTRICAL INTERFERENCE
Do not place the GNSS antenna near the following sources of electrical and
magnetic noise:
•
Gasoline engines (spark plugs)
•
Televisions and computer monitors
•
Alternators and generators
•
Electric motors
•
Equipment with DC-to-AC converters
•
Fluorescent lights
•
Switching power supplies
•
Arc welding equipment
4.1.3. UNINTERRUPTABLE POWER SUPPLY
CHC recommends that you use an uninterruptible power supply (UPS) to
P5E GNSS Reference Receiver User Guide
 Page

4. Setting Up the Receiver
power the receiver. The internal battery can also operate as a UPS for up to
24 hours. A UPS protects the equipment from power surges and spikes, and
keeps the receiver running during short power outages.
For more information, contact your local CHC dealer.
4.1.4. LIGHTING AND SURGE PROTECTION
CHC recommends that you install lightning protection equipment at
permanent sites. All connections to the receiver should have surge
protection. Typically, the minimum protection should include a surge
protector in the antenna feed line, on the receiver's power supply system. If
serial devices are attached to the receiver, those serial connections should
also be provided with surge protection. Also, protect any communications
and power lines at building entry points. If you use other antennas, such as a
radio modem that distributes real-time correction messages, install surge
protection on those antenna feeds as well.
No surge protection devices can offer protection unless they are connected
to an excellent ground using very low impedance conductors. Equipment
damage caused by electrical surges occurs in many permanent installations
even though surge protection is in place. Commonly, this is because the
grounding system used was designed to protect against AC electrical hazards
rather than to dissipate the sudden, high current surges caused by lightning.
Please consult with a lightning protection expert or research the topic when
planning permanent installations.
For more information, contact your local CHC dealer.
4.1.5. PLACING THE ANTENNA
The antenna location will have a significant effect on the quality of your P5E
receiver's performance. In temporary developments it may not always be
possible to set up on an ideal location with an excellent sky view. However,
when installing a permanent station, be sure to plan the antenna location
and mounting system carefully.
The general requirements for the antenna location and mount are:
•
Keep the distance from the objects that may cause the multipath effects
(such as buildings, trees, reflective surface) for at least 200 m (656 feet)
•
Clear sky above 10 degrees elevation
•
Away from electromagnetism interference region (e.g. Microwave
station, radio transmitting station, high voltage wires) at least 200 m
(656 feet)
•
Mounted 1.5 m (5 feet) above any nearby signal reflectors.

You can configure the P5E GNSS reference receiver to perform a wide variety
of functions. This chapter describes the configuration methods other than
the front panel display, and explains when and why each method is used.
The WinFlash utility described in this chapter is used primarily to update the
receiver firmware.
6.1. CONFIGURING THE ETHERNET SETTINGS
The receiver Ethernet port connects to an Ethernet network, through which
you can access, configure, and monitor the receiver. No serial cable
connection to the receiver is necessary.
The receiver has the following Ethernet settings:
•
IP address
•
IP mask
•
Gateway
•
DNS server
•
HTTP port
The default setting for the HTTP port is 80: This port is not assigned by the
network. HTTP port 80 is the standard port for web servers and enables you
to connect to the receiver by entering only the receiver’s IP address in a web
browser.
For example, using port 80: http://192.168.32.132
If the receiver is set to use a port other than 80, you must enter the IP
address followed by the port number in a web browser.
For example, port 9971: http://192.168.32.132:9971
Users can configure the Ethernet settings through the front panel (see 5.4.
Setting up the receiver as part of an Ethernet configuration) and a web
server. To use a web server, the receiver must be connected to a network
and have a valid Ethernet configuration.
NOTE: The receiver should be configured the Ethernet settings
through the front panel for its first connection to the Internet.

7. DEFAULT SETTING AND CONFIGURATION FILES
Most of the receiver settings are stored in application files. The default
application file, Default.cfg, is stored permanently in the receiver, and
contains the factory default settings for the P5E GNSS reference receiver.
Whenever the receiver is reset to its factory defaults, the current settings
(stored in the current configuration file, copy.cfg) are reset to the values in
the default application file.
The P5E GNSS reference receiver extends the use of configuration files to
allow simplified receiver setting duplication in multiple receivers. This is
sometimes referred to as receiver cloning and is very useful when preparing
a large group of receivers for a field data collection campaign.

7.1.2. USING CONFIGURATION FILES TO DUPLICATE RECEIVER SETTINGS
The P5E GNSS reference receiver allows the extensive use of application files
in order to retain a unique receiver configuration. With this receiver, you can
create a configuration file that includes most of the receiver's unique
configuration settings. You can then update that configuration file onto one
or more other P5E GNSS reference receivers to quickly configure them to
match the receiver which creates that configuration file.
NOTE: The configuration file includes most of the configuration
settings except IP Address, IP Mask, Gateway and DNS Server.
This is called receiver configuration cloning or cloning. Receiver cloning
greatly reduces the time required to prepare a large group of receivers for
field operations.

D. GLOSSARY
base station
Also called reference station. A base station in construction, is a receiver placed at
a known point on a jobsite that tracks the same satellites as an RTK rover, and
provides a real-time differential correction message stream through radio to the
rover, to obtain centimeter level positions on a continuous real-time basis. A base
station can also be a part of a virtual reference station network, or a location at
which GPS observations are collected over a period of time, for subsequent
postprocessing to obtain the most accurate position for the location.
carrier
A radio wave having at least one characteristic (such as frequency, amplitude, or
phase) that can be varied from a known reference value by modulation.
carrier frequency
The frequency of the unmodulated fundamental output of a radio transmitter. The
GPS L1 carrier frequency is 1575.42 MHz.
carrier phase
The time taken for the L1 or L2 carrier signal generated by the satellite to reach
the GPS receiver. Measuring the number of carrier waves between the satellite
and receiver is a very accurate method of calculating the distance between them.
CMR
Compact Measurement Record. A real-time message format developed by Trimble
CMR+
for broadcasting corrections to other Trimble mainboard receivers. CMR is a more
efficient alternative to RTCM.
DGPS
See real-time differential GPS.
differential
Differential correction is the process of correcting GPS data collected on a rover
correction
with data collected simultaneously at a base station. Because the base station is
on a known location, any errors in data collected at the base station can be
measured, and the necessary corrections applied to the rover data.
Differential correction can be done in real-time, or after the data has been
collected by postprocessing.
Differential GPS
See real-time differential GPS.
DOP
Dilution of Precision. A measure of the quality of GPS positions, based on the
geometry of the satellites used to compute the positions. When satellites are
widely spaced relative to each other, the DOP value is lower, and position accuracy
is greater. When satellites are close together in the sky, the DOP is higher and GPS
positions may contain a greater level of error.
PDOP (Position DOP) indicates the three-dimensional geometry of the satellites.
Other DOP values include HDOP (Horizontal DOP) and VDOP (Vertical DOP), which
indicate the accuracy of horizontal measurements (latitude and longitude) and
vertical measurements respectively. PDOP is related to HDOP and VDOP as
follows:
PDOP² = HDOP² + VDOP²
dual-frequency
A type of receiver that uses both L1 and L2 signals from GPS satellites. A
GPS
dual-frequency receiver can compute more precise position fixes over longer
distances and under more adverse conditions because it compensates for
ionospheric delays.
EGNOS
European Geostationary Navigation Overlay Service. A satellite-based
augmentation system (SBAS) that provides a free-to-air differential correction
service for GPS.
EGNOS is the European equivalent of WAAS, which is available in the United

States.
elevation mask
The angle below which the receiver will not track satellites. Normally set to 10
degrees to avoid interference problems caused by buildings and trees, and
multipath errors.
ephemeris /
A list of predicted (accurate) positions or locations of satellites as a function of
ephemerides
time. A set of numerical parameters that can be used to determine a satellite’s
position.
Available as broadcast ephemeris or as postprocessed precise ephemeris.
epoch
The measurement interval of a GPS receiver. The epoch varies according to the
measurement type: for real-time measurement it is set at one second; for
postprocessed measurement it can be set to a rate of between one second and
one minute. For example, if data is measured every 15 seconds, loading data using
30-second epochs means loading every alternate measurement.
firmware
The program inside the receiver that controls receiver operations and hardware.
GLONASS
Global Orbiting Navigation Satellite System. GLONASS is a Soviet space-based
navigation system comparable to the American GPS system. The operational
system consists of 21 operational and 3 non-operational satellites in 3 orbit
planes.
GNSS
Global Navigation Satellite System.
GSOF
General Serial Output Format. A Trimble proprietary message format.
HDOP
Horizontal Dilution of Precision. HDOP is a DOP value that indicates the accuracy
of horizontal measurements. Other DOP values include VDOP (vertical DOP) and
PDOP (Position DOP).
Using a maximum HDOP is ideal for situations where vertical precision is not
particularly important, and your position yield would be decreased by the vertical
component of the PDOP ( for example, if you are collecting data under canopy).
L1
The primary L-band carrier used by GPS satellites to transmit satellite data.
L2
The secondary L-band carrier used by GPS satellites to transmit satellite data.
L5
The third L-band carrier used by GPS satellites to transmit satellite data. L5 will
provide a higher power level than the other carriers. As a result, acquiring and
tracking weak signals will be easier.
MSAS
MTSAT Satellite-Based Augmentation System. A satellite-based augmentation
system (SBAS) that provides a free-to-air differential correction service for GPS.
MSAS is the Japanese equivalent of WAAS, which is available in the United States.
multi-frequency
A type of receiver that uses multiple carrier phase measurements (L1, L2, and L5)
GPS
from different satellite frequencies.
multipath
Interference, similar to ghosts on a television screen that occurs when GPS signals
arrive at an antenna having traversed different paths. The signal traversing the
longer path yields a larger pseudorange estimate and increases the error. Multiple
paths can arise from reflections off the ground or off structures near the antenna.
NMEA
National Marine Electronics Association. NMEA 0183 defines the standard for
interfacing marine electronic navigational devices. This standard defines a number
of 'strings' referred to as NMEA strings that contain navigational details such as
positions. Most CHC GPS receivers can output positions as NMEA strings.
PDOP
Position Dilution of Precision. PDOP is a DOP value that indicates the accuracy of

three-dimensional measurements. Other DOP values include VDOP (vertical DOP)
and HDOP (Horizontal Dilution of Precision).
Using a maximum PDOP value is ideal for situations where both vertical and
horizontal precision are important.
postprocessing
Postprocessing is the processing of satellite data after it has been collected, in
order to eliminate error. This involves using computer software to compare data
from the rover with data collected at the base station.
real-time
Also known as real-time differential correction or DGPS. Real-time differential GPS
differential
is the process of correcting GPS data as you collect it. Corrections are calculated at
GPS
a base station and then sent to the receiver through a radio link. As the rover
receives the position it applies the corrections to give you a very accurate position
in the field.
Most real-time differential correction methods apply corrections to code phase
positions. RTK uses carrier phase measurements.
While DGPS is a generic term, its common interpretation is that it entails the use
of single-frequency code phase data sent from a GPS base station to a rover GPS
receiver to provide sub-meter position accuracy. The rover receiver can be at a
long range (greater than 100 km (62 miles)) from the base station.
reference station
See base station
rover
A rover is any mobile GPS receiver that is used to collect or update data in the
field, typically at an unknown location.
RTCM
Radio Technical Commission for Maritime Services. A commission established to
define a differential data link for the real-time differential correction of roving GPS
receivers. There are three versions of RTCM correction messages. All CHC GPS
receivers use Version 2 protocol for single-frequency DGPS type corrections.
Carrier phase corrections are available on Version 2, or on the newer Version 3
RTCM protocol, which is available on certain CHC dual-frequency receivers. The
Version 3 RTCM protocol is more compact but is not as widely supported as
Version 2.
RTK
Real-time kinematic. A real-time differential GPS method that uses carrier phase
measurements for greater accuracy.
SBAS
Satellite-Based Augmentation System. SBAS is based on differential GPS, but
applies to wide area (WAAS/EGNOS and MSAS) networks of reference stations.
Corrections and additional information are broadcast via geostationary satellites.
signal-to-noise
SNR. The signal strength of a satellite is a measure of the information content of
ratio
the signal, relative to the signal’s noise. The typical SNR of a satellite at 30°
elevation is between 47 and 50 dBHz. The quality of a GPS position is degraded if
the SNR of one or more satellites in the constellation falls below 39.
skyplot
The satellite skyplot confirms reception of a differentially corrected GPS signal and
displays the number of satellites tracked by the GPS receiver, as well as their
relative positions.
SNR
See signal-to-noise ratio
UTC
Universal Time Coordinated. A time standard based on local solar mean time at
the Greenwich meridian.
VRS
Virtual Reference Station. A VRS system consists of GNSS hardware, software, and

D. Glossary
communication links. It uses data from a network of reference stations to provide
corrections to each rover that are more accurate than corrections from a single
base station.
To start using VRS corrections, the rover sends its position to the VRS server. The
VRS server uses the reference station data to model systematic errors (such as
ionospheric noise) at the rover position. It then sends RTCM or CMR correction
messages back to the rover.
WAAS
Wide Area Augmentation System. WAAS was established by the Federal Aviation
Administration (FAA) for flight and approach navigation for civil aviation. WAAS
improves the accuracy and availability of the basic GPS signals over its coverage
area, which includes the continental United States and outlying parts of Canada
and Mexico.
The WAAS system provides correction data for visible satellites. Corrections are
computed from ground station observations and then uploaded to two
geostationary satellites. This data is then broadcast on the L1 frequency, and is
tracked using a channel on the GPS receiver, exactly like a GPS satellite.
Use WAAS when other correction sources are unavailable, to obtain greater
accuracy than autonomous positions. For more information on WAAS, refer to the
FAA website at http://gps.faa.gov.
The EGNOS service is the European equivalent and MSAS is the Japanese
equivalent of WAAS.
