Unicore UM440 High Precision GNSS Chipset

GPS/GLONASS/Galileo/BeiDou High Precision RTK Module

REQUEST PRICING

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.

Features

  • Supports GPS L1 + GLONASS L1 + Galileo E1 + BeiDou B1
