UM981

GPS/BDS/GLONASS/Galileo/QZSS All-constellation Multi-frequency RTK/INS Integrated Positioning Module

Unicore's new-generation proprietary RTK/INS integrated navigation module. The module integrates a high-speed floating-point processor and an RTK-dedicated coprocessor, enabling it to output IMU raw data at 100Hz and RTK data at 50Hz, respectively. The on-board MEMS chip and algorithm ensure continuous, high-quality positioning results in GNSS denied environments such as buildings, tunnels, overpasses, and shaded areas. With its high precision and performance, the UM981 is well-suited for surveying and precision agriculture, among other applications.
