Introduction
1.1
Overview
UM4B0 is a high precision positioning and heading RTK module developed by
Unicore Communications, targeting light robots, UAVs, intelligent vehicles, GIS
information collection, etc.
By employing a single UC4C0 (432 channel tracking) baseband chip and a single RF
chip, using single-sided SMD packaging, UM4B0 has achieved the smallest size
(30x40mm) in this industry with high accuracy heading and positioning output. It can
simultaneously track BDS B1I/B2I/B3I/B1C/B2a + GPS L1/L2/L5 + GLONASS
L1/L2+Galileo E1/E5a/E5b.
