UM981/UM981S

UM981 is Unicore's new-generation proprietary RTK and INS integrated navigation module. It can simultaneously track multiple satellite systems and frequencies, including GPS, BDS, GLONASS, Galileo, QZSS, NavIC 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 when loss of lock on GNSS signals occurs, providing high-quality positioning results in complex environments such as building blocks, tunnels, overpasses and tree shades. UM981 and UM981S are designed for high-precision navigation and positioning application, with UM981 for precision agriculture and UM981S for surveying and mapping, respectively.
