UM332

BDS/GPS/GLONASS/GALILEO Quad-System High Precision Heading Module

Brief Introduction

UM332 is the high precision orientation and positioning module developed by Unicore Communications, targeting light Roberts, drones, intelligent vehicles, GIS information collection, etc. By employing the single UC4C0 baseband chip and broadband frequency chip, the first multi-system multi-frequency point module
level GNSS high precision product in the industry has been achieved. It can simultaneously track BDS B1/B2/B3 + GPS L1/L2/L5 + GLONASS L1/L2+Galileo E1/E5a/E5b. Equipped with the smallest size, it is also very competitive in terms of cost and power dissipation, etc. The anti-interference capability and initial navigation of UM332 narrowband enable it to maintain excellent application experience even in some harsh environment.
