UM440 BDS/GPS/GLN/Gal High precision RTK Module


 
General 
Product Name:UM440 BDS/GPS/GLN/Gal High precision RTK Module
Product Description:UM440 is the low cost high precision RTK module developed by Unicore, targeting agriculture, drones, GIS market, etc. By employing a single UC4C0 (432 channel tracking) baseband chip and a single RF chip, using single-sided SMD packaging, UM440 achieve cost effective high precision performance. It can simultaneously track GPS L1/BDS B1/GLONASS L1/Galileo E1. Under 10km baseline, UM440 can maintain excellent application experience in challenging environments such as urban canyons, by deploying anti-interference function block and on board MEMS device.
