The RB31E is an AEC-Q100 qualified dual-band GNSS module, with integrated multi-band RTK technology for centimeter-level accuracy. The module features the STMicroelectronics® 5th generation positioning receiver platform with 80 tracking channels and 4 fast acquisition channels, compatible with up to 4 constellations (GPS, GLONASS, Galileo and BDS) as well as QZSS.
The RB31E provides dead reckoning capabilities with an integrated inertial measurement unit (IMU) to provide continual, highly precise positioning. The integrated state-of-the-art algorithms fuse the IMU data, GNSS measurements, wheel tick sensor input and vehicle dynamics, to provide lane-accurate positioning where GNSS alone would fail. The module supports standard RTCM corrections from 3rd party base stations or correction networks to achieve centimeter-level positioning in seconds, allowing it to perform excellently under challenging conditions such as urban canyons.
The RB31E is designed for easy integration with minimal e-BOM and is well-suited for mass market adoption. Due to its compact design, light weight, and low power consumption, it is ideal for vehicle markets such as automotive navigation, ADAS and V2X, as well as applications in precision smart agriculture.
