2.7 Downloading Logged Data
Data logging involves the collection of GNSS measurement data over a period at a
static point or points, and subsequent post-processing of the information to accurately
compute baseline information. Data logging using receivers requires access to suitable
GNSS post-processing software such as the CHC Geomatics Office (CGO) Software.
The procedures of downloading logged data in the receiver are as follows:
Switch on the receiver and connect it with a computer by USB Cable. After the
successful connection, a removable disk named as the Serial Number (SN) of the
receiver will appear on the computer.
Double click the removable disk and you will see the folder named as “repo”.
Double click this folder, you will see 9 folders. The “push_log” folder is used to
save the log files, and the other 8 folders represent different logging session and
are used for store static data.
Double click the folder that you have configured to store the static data, you will
see the folder(s) created by the E91 system automatically and named by the date
which is decide by GPS time when you start to log data.
Select the destination folder and double click it, and then two folders named as
different data format (hcn and rinex) will be displayed.
Select the data format that you has configured to save the static data, you will find
the static raw data.
Getting Started with E91
21
Tip – For hcn files, the name of the file is represented as XXXXXXDDDNN, where
XXXXXX is the SN of the receiver, DDD is day of year, and NN is the recording session.
WARNING – The static data will be saved in the first logging session, the
“record_1” folder, by default. Old files will be deleted if the storage space is full. If you
configure not to auto delete old files when the memory is low, the receiver will stop
data logging.
Base Station Setup and Operation
22
3 Base Station Setup and Operation
Real-Time Kinematic (RTK) operation provides centimeter-level precision by
eliminating errors that are present in the GNSS system. For all RTK operations, you
require both a rover receiver and a source of corrections from a base station or
network of base stations.
A base station consists of a receiver that is placed at a known point. The receiver tracks
the same satellites that are being tracked by the rover receiver simultaneously. Errors
in the GNSS system are monitored at the base station, and a series of position
corrections are computed. The messages are sent through a radio link to the rover
receiver, where they are used to correct the real time positions of the rover.
This chapter provides the information to help you identify good setup locations,
outlines basic precautions that you need to take to protect the equipment, and
describes the conventional process to set up the base station and the configuring
procedure that required for transmitting correction data.
3.1 Base Station Setup Guidelines
For good performance, the following base station setup guidelines are recommended:
• Place the GNSS receiver in a location on the worksite where equal range in all
directions provides full coverage of the site.
• Place the GNSS antenna in a location that has a clear line of sight to the sky in all
directions. Do not place the antenna near vertical obstructions such as buildings,
deep cuttings, site vehicles, towers, or tree canopy.
• The GNSS antenna must have a dear line of sight to the sky at all times during
operation.
• Place the GNSS and radio antennas as high as practical. This minimizes multipath
from the surrounding area, and enables the radio to broadcast to the maximum
distance.
• Choose the most appropriate radio antenna for the size of the worksite. The
higher the gain on the antenna, the longer the range.
• Make sure that the GNSS receiver does not lose power. To operate continuously
for more than a few hours without loss of power at the base station, provide
external power. When you use an external power supply, the integrated battery
provides a backup power supply, enabling you to maintain continuous operation
through a mains power failure.
• Do not locate a GNSS receiver, GNSS antenna, or radio antenna within 400
meters (about 1,300 feet) of transmitters, such as a power radar or cellular
Base Station Setup and Operation
23
communications tower.
• Do not set up the base station close to the sources of electromagnetic
interference, include alternators and generators, electric motors, equipment
with DC-to-AC converters, etc.
• Do not operate the receiver outside the specified operating temperature range -
40°C to +60°C (-40°F to +140°F).
• Take reasonable care to keep the GNSS receiver equipment dry, which could
prolong their life and reduce the effects of corrosion on ports and connectors.
3.2 Outputting Corrections Using Internal Radio Modem
3.2.1 Base Station Setup
1. Connect the radio antenna onto E91 receiver. Screw the receiver onto
extension pole.
2. Screw the extension pole with auxiliary H.I. tool onto tribrach adaptor.
3. Mount the tribrach onto the tripod.
4. Insert the tribrach adaptor into the tribrach.
5. Level and plumb the receiver over the known (control) point.
6. Measure the height of the base station GNSS antenna by measuring the slant

4 Rover Station Setup And Operation
Real-Time Kinematic (RTK) operation provides centimeter-level precision by
eliminating errors that are present in the GNSS system. For all RTK operations, you
require both a rover receiver and a source of corrections from a base station or
network of base stations.
The second part of the RTK GNSS system is the rover receiver. The rover receiver is
moved between the points that require measurement or stakeout. The rover receiver
is connected to a base station or to a source of RTK corrections such as a CORS
(Continuous Operational Reference System) or the CHC APIS service. The connection
is provided by:
• an integrated radio
• an integrated cellular modem
• a cellular modem in the controller
This chapter provides the information to help you identify good setup locations,
describes the conventional process to set up the rover station and the configuring
procedure that required for receiving correction data.
4.1 Rover Station Setup Guidelines
For good rover operation, observe the following setup guidelines:
• Place the GNSS antenna in a location that has a clear line of sight to the sky in
all directions. Do not place the antenna near vertical obstructions such as
buildings, deep cuttings, site vehicles, towers, or tree canopy. GNSS rovers and
the base station receive the same satellite signals from the same satellites. The
system needs five common satellites to provide RTK positioning.
WARNING – Take care not to touch overhead power lines with the CHC E91
GNSS receiver or the range pole when moving the equipment into position.
Touching overhead power lines may cause electrocution, leading to serious injury.
• GNSS satellites are constantly moving. Because you cannot measure at a
specific location now does not mean that you will not be able to measure there
later, when satellite coverage at the location improves.
• To get a fixed position solution with centimeter precision, initialize the RTK
rover receiver. For initialization to take place, the receiver must track at least
five satellites that the base station is also tracking. In a dual-satellite
constellation operation, for example, GPS and GLONASS, the receiver must
Rover Station Setup And Operation
26
track at least six satellites.
• To continue to survey at centimeter precisions, the rover must continuously
track at least four satellites that the base station is also tracking. The radio link
between the base and rover receivers must also be maintained.
• Loss of the satellite signals will result in a loss of centimeter position precision.
4.2 Rover Station Setup
1. If required, connect the radio antenna onto E91 receiver.
2. Screw the receiver on top of the range pole.
3. Fix the controller bracket on the range pole.
4. Fit the controller in the controller bracket.
5. Level and plumb the receiver over the target measuring point.
