OVERVIEW This chapter introduces the X360 GIS Receiver (“the Receiver”). This Receiver makes it easy to set up a powerful and reliable Continuously Operating 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 Station Network (CRNet) software. As part of a permanent A temporary field base station to broadcast RTK corrections and collect station with or without supporting software. observations for post processing. B.I. RECEIVER FRAMEWORK The Receiver integrates the multi-frequency GNSS technology into a specialized processing and communications framework. The Receiver can operate as a standalone 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 s 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". X360 GIS Reference Receiver User Guide Page 3. Batteries and Power B.I.i. 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 X360 GIS 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: Use ... HTT FTP To perform... 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. B.II. 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. X360 GIS Reference Receiver User Guide Page 10 3.

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. B.V. ELECTRONIC INTERFACE X360 GIS Reference Receiver User Guide Page 11 3. Batteries and Power 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. Avoid locating the Receiver or antenna within 400 meters of powerful radar, television, or other transmitters or GNSS antennas. Low-power transmitters, such as those in cell phones and two-way radios, normally do not interfere with Receiver operations. B.VI.

Connect the Receiver to a computer to download files from the Receiver (as external storage equipment) to the computer C. BATTERIES AND POWER The X360 GIS 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 17 hours operation. NOTE–All battery operational tests are carried out with new, fully-charged batteries at room temperature, tracking both GPS 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. X360 GIS Reference Receiver User Guide Page 14 3. Batteries and Power C.I. EXTERNAL POWER The Receiver uses an external power source in p 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. The Receiver’s internal battery charges only when the external voltage is above 11 V DC. CHC recommends that the applied external power offers between 12 V DC and 36 V DC and is able to supply at least 4 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. C.II. 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. X360 GIS Reference Receiver User Guide Page 15 3. Batteries and Power 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. C.III. BATTERY PERFORMANCE To optimize battery performance and extend battery life: Fully charge all new batteries before use. C.IV. 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: 6. 7. Do not charge or use the battery if it appears to be damaged or leaking. Charge the Lithium-ion battery only within the X360 Receiver. The X360 GIS Reference Receiver User Guide Page 16 3. Batteries and Power battery can only be removed by an authorized CHC Service Center. C.V. 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. The internal battery will only charge from an external power source that delivers more than 11 V, for example, an AC power adaptor. 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 12 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 17 hours after a power failure. C.VI. 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. X360 GIS Reference Receiver User Guide Page 17 D. 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 station composed of X360 GIS 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. D.I. GUIDELINES When you set up the Receiver, follow these guidelines. D.I.i. ENVIRONMENTAL CONDITIONS The Receiver has a waterproof housing but you must take reasonable care to keep the unit dry. To improve the performance and long-term reliability of the Receiver, do not expose the Receiver to extreme environmental conditions, such as: Water Corrosive fluids and gases D.I.ii. 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 D.I.iii. UNINTERRUPTABLE POWER SUPPLY CHC recommends that you use an uninterruptible power supply (UPS) to X360 GIS Reference Receiver User Guide Page 18 6. Configuring the Receiver: Other Than Keypad and Display power the Receiver. The internal battery can also operate as a UPS for up to 17 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. D.I.iv. 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. D.I.v. PLACING THE ANTENNA The antenna location will have a significant effect on the quality of your X360 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.

Glossary base station GLOSSARY Also called 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 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 carrier radio wave having at least one characteristic (such as frequency, amplitude, location. or phase) that can be varied from a known carrier frequency value by modulation. 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 Compact Measurement Record.

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- A type of Receiver that uses both L1 and L2 signals from GPS satellites. A frequency dual-frequency Receiver can compute more precise position fixes over GPS longer distances and under more adverse conditions because it compensates for ionospheric delays. 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. X360 GIS Reference Receiver User Guide Page 56 ephemeri D.

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 GNSS The program inside the Receiver that controls Receiver operations and hardware. 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 L1 The primary L-band carrier used by GPS satellites to transmit satellite data. canopy). 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. multi- A type of Receiver that uses multiple carrier phase measurements (L1, L2, and frequency L5) from different satellite frequencies. multipath GPS Interference, similar to ghosts on a television screen that occurs when GPS signals arrive at an antenna having traversed different paths.

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 PDOP Position strings. Dilution of Precision. PDOP is a DOP value that indicates the accuracy of X360 GIS Reference Receiver User Guide Page 57 D. Glossary 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- Also known as real-time differential correction or DGPS. Real-time differential time GPS is the process of correcting GPS data as you collect it. Corrections are differen calculated at a base station and then sent to the Receiver through a radio link. tial GPS 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 station rover See station basebase station. 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 RTK Real-time kinematic. A real-time widely supported as Version 2. differential GPS method that uses carrier phase measurements for greater accuracy. signal-to- SNR. The signal strength of a satellite is a measure of the information content noise ratio of 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 skyplot The 39. 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 Station. A VRS system consists of GNSS hardware, software, and X360 GIS Reference Receiver User Guide Page 58 D. Glossary communication links. It uses data from a network of 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 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.
