Description
Overview
The Unicore UM440 high precision GNSS chipset is the low cost RTK module developed by Unicore Communications, targeting agriculture, drones, etc. By employing a single UC4C0 (432 channel tracking) baseband chip and a single RF chip and using single-sided SMD packaging, UM440 achieve cost effective performance. It can simultaneously track GPS L1 + GLONASS L1 + Galileo E1 + BeiDou B1. Under a 10 km baseline, UM440 can maintain excellent application experience in challenging environments such as urban canyons, by deploying anti-interference functions and an onboard MEMS device.
