It features a concurrent multi-constellation GNSS receiver on dual GNSS bands, an integrated 6-axis sensor, fusion with Real-Time Kinematic (RTK) and Dead-Reckoning (DR). The module can achieve sub-meter-level accuracy in open-sky areas.The GNSS board can work on L1 and L5 bands for GPS, Galileo and QZSS, L1 band for GLONASS and BeiDou, and L5 band for IRNSS. This greatly increases the number of satellites which can be involved in tracking and positioning, thereby significantly reducing the multipath effect from tall buildings in urban environments, reducing signal acquisition time and improving positioning accuracy. In addition to this the GNSS module’s on-board LNAs and SAW filters serve to ensure better positioning in weak signal areas and harsh environments.The GNSS module’s combination of compact design, low power consumption and high performance makes it a popular choice for real-time tracking systems for vehicles, people and assets, as well as for sharing economy applicationsFeature Highlights•Support dual-band and multi-constellation•Supports GPS/BeiDou/GLONASS/Galileo/IRNSS/QZSS•High-performance, high reliability positioning engine. It facilitates a fast and precise GNSS positioning capability.•Supports serial communication interfaces UART and SPI.•Integrates a 6-axis MEMS sensor and supports sophisticated Real-Time Kinematic (RTK) and Dead-Reckoning (DR) algorithms to fuse the sensor data, GNSS raw data and speed data, etc. to provide sub-meter level positioning accuracy in an open-sky environment•Support AGNSS•Embedded flash memory provides the capacity for storing user-specific configurations and future firmware updates.3Typical Applications•High-precision GNSS for Tracking and Positioning•Navigation where GNSS signal is not available•6-axis sensor (3-axis accelerator and 3-axis gyroscope)•Internet of things4GNSS ConstellationsThe GNSS module is a dual-band GNSS receiver that can receive and track GPS, BeiDou, GLONASS, Galileo, QZSS, IRNSS signals.4.1GPSThe module is designed to receive and track GPS L1 C/A signals (1574.397–1576.443 MHz) and L5 signals (1166.22–1186.68 MHz) provided by GPS.4.2BeiDouThe module is designed to receive and track BeiDou B1I (1559.052–1563.144 MHz) and B2a (1155.99–1196.91 MHz). The ability to receive and track BeiDou signals in conjunction with GPS results in higher coverage, improved reliability, and better accuracy.4.3GLONASSThe module is designed to receive and track GLONASS L1 signals (1597.781–1605.656 MHz) provided by GLONASS.4.4GalileoThe module is designed to receive and track Galileo E1 (1573.374–1577.466 MHz) and E5a (1166.22–1186.68 MHz) signals provided by Galileo.4.5IRNSSThe Indian Regional Navigation Satellite System (IRNSS) or NavIC is a regional navigation satellite system that transmits additional L5 signals for complying with the requirements of an independent accurate positioning system for users in India. The GNSS module is designed to receive and track IRNSS L5 signals (1175.427–1177.473 MHz) from IRNSS satellites.4.6QZSSThe Quasi-Zenith Satellite System (QZSS) is a regional navigation satellite system that transmits additional GPS L1 C/A signals for the Pacific region covering Japan and Australia. The GNSS module can detect and track these signals concurrently with GPS signals, resulting in better availability especially under challenging conditions, e.g., in urban canyons.5Augmentation System5.1SBASThe GNSS module supports SBAS (Satellite-Based Augmentation System) broadcast signal reception, and GPS data are complemented by additional regional or wide area GPS enhancement data. The system enhances the data through satellite broadcasting, and this information can be used in GNSS receivers to improve the accuracy of the results. SBAS satellites can also be used as additional signals for ranging or distance measurement, further improving availability. Supported SBAS systems: WAAS, EGNOS, MSAS and GAGAN.5.2AGNSSThe module supports AGNSS feature that significantly reduces the module’s TTFF, especially under lower signal conditions. To implement AGNSS feature, the module should get the assistance data including the current time, rough position, and LTO data.5.3Real-Time Kinematic (RTK)The GNSS module modules support RTK functionality as rovers. Before supporting the RTK navigation technique, the module needs to receive the RTK correction messages via its UART port. RTK correction messages can be delivered either using a cellular module or other terrestrial network technology. In default configuration, the module will attempt to achieve the best positioning accuracy based on the correction data that it receives. When the module receives an input stream of RTCM messages, it enters RTK float mode. Once it fixes carrier phase ambiguities, the module enters the RTK fixed mode.The module may be expected to achieve sub-meter level accuracy only when it is in RTK fixed mode. If the module loses the carrier phase lock, at the minimum semaphore required to maintain the RTK fixed mode, it returns to the RTK float mode. The module will also continue to try to resolve carrier phase ambiguity and return to RTK fixed mode after restoring the minimum semaphore.The current mode of operation is set by the associated NMEA messages.5.4Odometer (ODO)The FWD hardware input is used to input vehicle forward/backward status signals. When it is at low voltage level, the vehicle is moving forward, and when it is at high level, it is moving backward.The WHEELTICK hardware input is used to input odometer signals from a vehicle. It can be sampled from the wheel revolution sensors or the transmission of the vehicle.Only cars need to be connected to the FWD signal, electric bicycles do not.5.5GeofencingThe GNSS module supports geofence areas, defined on the Earth's surface using a 2D model. Geofencing is active when at least one geofence area is defined. The current status can be found by polling the receiver. The receiver evaluates whether the current location of each region is within that region or not and signals its status via GEOFENCE pin. Geofencing feature can be configured using geofence messages. The evaluation is activated whenever one or more geofences are configured.5.6Dead Reckoning FunctionDead Reckoning is the process of estimating the module’s current position based on the last position obtained from GNSS, speed, heading sensor data, etc. With this combined sensor inputs, the system plots the navigation trace when the satellite signals are partially or completely blocked while satellite signals provide updates and correction for sensor drift. With this technology, the system obtains continuous and high-accuracy positioning in environments such as tunnels and urban canyons.In addition, the module supports output of sensor raw data through UART to support your applications such as driving behavior analysis.6Hardware Board and Case DiagramPin # Feature Direction DescriptionJ3-1 RESET_N Input Resets GNSS moduleJ3-2 WHEELTICK Input Odometer wheel-tick inputJ3-3 1PPS Output One pulse per secondJ3-4 FWD Input Forward/Backward directionJ3-5 GPS_EN Input Enable the GNSS moduleJ3-6 SDA Input/Output I2C data.
