Note : Your request will be directed to Unicore Communications.

The UM482 is a multi-band GNSS module with integrated multi-band Real Time Kinematics (RTK) technology for light-weight robots, GIS, intelligent driving, UAV applications. It concurrently uses GNSS signals from BDS B1/B2, GPS L1/L2, GLONASS L1/L2, Galileo E1/E5b, and QZSS L1/L2 constellations. This multi-band GNSS receiver is based on Nebulas-II SoC that supports 432 channels, two 600 MHz ARM processors, and dedicated high-speed floating-point coprocessors, for powerful satellite signal processing. It adopts Unicore’s new-generation “UGypsophila” RTK processing technology and takes advantage of the high-performance data sharing capability and super-simplified operating system within the Nebulas II GNSS SoC. This module delivers centimeter-level accuracy in seconds by combining GNSS signals from multiple frequency bands (L1/L2/L5) and RTK technology. It requires a DC supply of 3.3 V and consumes 2.4 W of power.

The UM482 performs pattern matching recognition and correction algorithm with the internally abstracted RTCM protocol template to fully implement the differential RTCM input adaptation function. Upon the RTCM data access, it judges quickly the input COM port and RTCM3.2/3.0/2.3 format, without the need to specify the type of differential data, thus dramatically simplifying user operations. It performs sufficient optimization on the multi-dimensional RTK matrix pipeline computation, resulting in 80%+ higher RTK processing capability.

The UB482 integrates an onboard MEMS chip and uses the U-Fusion integrated navigation algorithm, to provide optimized continuity and reliability of heading/positioning output in complex environments like buildings, tunnels, and overpasses. It is available in an SMD package that measures 30 x 40 mm.
