Unicore UB482 Product Review

Developed by Unicore and based on the Nebulas-II high-performance high-precision GNSS SoC, the UB482 is a multi-system, multi-frequency, high-precision heading board. It supports BDS B1/B2 + GPS L1/L2 + GLONASS L1/L2 + Galileo E1/E5b + QZSS L1/L2. UB482 adopts classic compact size and supports network and inertial navigation. It is widely used in drones, driving tests and intelligent driving.

“UGypsophila” RTK processing technology

Coupled with a high-performance data-sharing capability and simplified operating system within the Nebulas  II,UB482 performs sufficient optimization on the multi-dimensional RTK matrix computation.The receiver will try to track all visible satellites of all systems to be used in the RTK and heading solutions, resulting in a shortened RTK initialisation time of 5 seconds and improved accuracy and reliability

Nebulas-II GNSS SoC

UB482 is based on Unicore’s Nebulas-II multi -system,multi-core,high precision SoC. The SoC supports 432 channels, includes a built-  in high performance ADC,ananti-interference unit,two 600 MHz ARM processors and two precision floating-point processing units, providing powerful GNSS signal processing capability. On-board MEMS integrated navigation The UB482 integrates 6-axison-board MEMS chipand U-FusionINS algorithm, resultingin optimized continuity and reliability of accurate heading and positioning out put in tough environments, such as city canyons,tunnels and overpasses.
