Brief Introduction
UM981 is Unicore’s new-generation proprietary RTK/INS integrated navigation module. It can simultaneously track multiple satellite systems and frequencies, including BDS B1I/B2I/B3I/B1C/B2a/B2b*, GPS L1/L2/L5, GLONASS G1/G2, Galileo E1/E5a/E5b, QZSS L1/L2/L5 and SBAS. The module integrates a high-speed floating point processor and an RTK dedicated coprocessor, being able to output positioning data at 100Hz. The on-board MEMS chip and U-Fusion integrated navigation algorithm ensure continuous positioning even when satellite signals are lost, providing high-quality positioning results in complex environments such as building blocks, tunnels, overpasses and tree shades. Due to its high precision and high performance, UM981 is well suited for intelligent driving, lawnmower, precision agriculture, etc.
