UM442 is cost efficient high precision RTK and heading module developed by Unicore Communications, Inc. UM442 can simultaneously track GPS, BDS,
GLONASS, Galileo. It also supports SBAS and QZSS.
The UM442 adopts Uincore new-generation Nebulas II chip and UGypsophila RTK algorithm. Based on high performance data-sharing technology and simplified operation system of Nebulas II chip, the UGypsophila RTK algorithm dramatically optimizes matrix processing. Therefore the UM442 can track many more satellites and shorten the initialization time to 5 seconds, with on-board MEMS and U-Fusion integrated navigation algorithm, UM442 can achieve accurate and reliable positioning and attitude determination, even in the most challenging environments such as urban canyons, tunnels etc.
