Overview
The Unicore UM4B0 high precision GNSS RTK module is a positioning and RTK module developed by Unicore Communications, targeting autonomous vehicles, GIS, etc.
By employing a single UC4C0 (432 channel tracking) baseband chip, a single RF chip and using single-sided SMD packaging, the UM4B0 is able to able to maintain the smallest form factor for heading and positioning solutions. It can simultaneously track GPS L1/L2/L5 + GLONASS L1/L2 + Galileo E1/E5a/E5b + BeiDou B1/B2/B3. It can maintain position in the most challenging environments such as urban canyons, by deploying anti-interference and the onboard MEMS device.
