Module

BDS/GPS/GLONASS/Galileo/QZSS

System-wide, full-frequency, high-precision positioning and orientation module

UM982 is a new generation BDS, GPS, GLONASS, Galileo, QZSS, SBAS system-wide, full-frequency, high-precision positioning and orientation module independently developed by Hexinxingtong. It is based on the integration of a new generation of radio frequency baseband and high-precision algorithms independently developed by Hexinxingtong. GNSS SoC chip—NebulasIV design. UM982 can simultaneously track BDS B11, B21, B31, GPS L1, L2, L5, GLONASSG1, G2, GalileoE1, E5a, E5b, QZSSL1, L2, L5 and other multi-frequency signals, and supports multi-system joint positioning and single-system independent positioning modes. , users can flexibly configure it. UM982 has a built-in advanced anti-interference unit, which can ensure reliable and accurate positioning accuracy even in complex electromagnetic environments. Mainly oriented to fields such as drones, lawn mowers, precision agriculture, and smart driving tests, it supports full-system, full-frequency spot on-chip RTK positioning and dual-antenna directional calculation, and can be used as a mobile station or base station.
