Overview

The Unicore UM442 high precision GNSS boardisa cost efficienthighprecisionRTKand heading moduledevelopedbyUnicoreCommunications, Inc. By employingUnicore’s new generation SOC chip Nebulas-II1, the UM442 can simultaneously track GPS, GLONASS, Galileo and BeiDou. It also supports SBAS and QZSS.

Powered by Unicore “UGypsophila” RTK processing technology, the UM442 tracks more satellites and performs optimization on the multi-dimensional RTK matrix computation, resulting in much higher RTK processing capability.UM442 has an onboard MEMS chip together with the U-Fusion integrated navigation algorithm. It can achieve accurate and reliable positioning and attitude sensing, even in the most challenging environments such as urban canyons, tunnels, etc.
