UM980

GPS/BDS/GLONASS/Galileo/QZSS All-constellation Multi-frequency High Precision RTK Positioning Module

Unicore's new-generation proprietary high-precision RTK positioning module. The module supports all currently available constellations and frequencies. It features a 50Hz RTK data update rate, and supports PPP, including E6 HAS and BDS B2b. With its excellent performance, UM980 is well-suited for high-precision surveying-grade applications, including surveying and mapping, precision agriculture, and deformation monitoring.
