OVERVIEW
The GCST20D-SSI is a concurrent multi-GNSS module supporting dead reckoning function. The module is equipped with a powerful GNSS core and a 6-axis IMU composed of a 3-axis accelerometer and a 3-axis gyroscope.
The GCST20D-SSI provides an outstanding performance and is easy to integrate. The module is designed and manufactured according to IATF 16949: 2016 standard.
The GCST20D-SSI supports GPS, GLONASS, Galileo, BDS and QZSS constellations. This multi-constellation feature guarantees accurate navigation in harsh environments such as dense urban canyons. The dead-reckoning feature enables reliable positioning performance, even when GNSS signals are absent or compromised. The integrated LNA improves the module’s performance under signal-challenging conditions.
Compared with single GPS system, the enabling of multiple GNSS systems generally increases the number of visible satellites, reduces the time to first fix and improves positioning accuracy while driving through dense urban canyon environment.
