DetailTechnical IndexDownloadHardware and Structu

Forsense NAV680-WP is a GNSS-IMU integrated unit for precise, continuous positioning of low-speed autonomous vehicles in lightly sheltered farms, orchards and scenic zones. Adopting self-developed IMU, fusion algorithms and multi-constellation UM982 module, it covers full bands of BDS, GPS, GLONASS, Galileo and QZSS. Requiring no wheel odometer, its vehicle-specific multi-model fusion algorithm outputs high-precision attitude, heading, position and speed for farm machines, inspection cars and tourist shuttles to guarantee stable full-scene autonomous driving performance.
