UM982C is Unicore's new-generation proprietary all-constellation, multi-frequency high-precision GNSS positioning and heading module, developed based on the GNSS SoC NebulaslV which integrates RF-baseband and high-precision algorithm. The module supports multiple frequencies of all systems, including GPS, BDS, GLONASS, Galileo, QZSS, NavlC, SBAS and L-Band, supports QZSS L6D (CLAS) PPP-RTK solution, and supports TruePoint REACH Sat L-band-based PPP-AR service.UM982C supportsdual-antenna heading solution, and can be used as a rover or a base station.
