GPS/BDS/GLONASS/GALILEO Multi-frequency High-precision RTK and Heading Board GPS/BDS/GLONASS/GALILEO Multi-frequency High-precision RTK and Heading Board

Brief Introduction

Developed by Unicore on basis of the Nebulas-II high-performance high-precision GNSS SoC, the UB482 is an quad-system octa-frequency high-precision headingboard with the 46x71mm, supporting the satellite signals including GPS L1/L2, BDS B1/B2, GLONASS L1/L2, GALILEO E1/E5b and SBAS. It is widely used in such application fields as drone, intelligent drive, precise agriculture and mechanical control.
■ New-generationNebulas-IISoCchip
The UB482 works with Unicore’s new-generation all-system multi-core high-precision GNSS SoC -- Nebulas-II. The chip supports 432 channels, two 600MHz ARM processors and dedicated high-speed floating-point coprocessors, achieving powerful satellite signal processing.
■ “UGypsophila”RTKprocessingtechnology
The UB482 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 NebulasII GNSS SoC. It performs sufficient optimization on the multi-dimensional RTK matrix pipeline computation, resulting in 80%+ higher RTK processing capability.
■ AdaptiverecognitionofRTCM
The UB482 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.
■ On-boardMEMSintegratednavigation
The UB482 integrates the on-board MEMS chip and U-Fusion integrated navigation algorithm, resulting in optimized continuity and reliability of heading/positioning output in such complex environments as buildings, tunnels and overpasses. Inputs of odometer and external higher-performance inertial components are supported
