Unicore UB4B0 Product Review

UB4B0 is a multi-system GNSS high-precision board based on a new-generation Nebulas-II high-performance GNSS SoC developed by Unicore Communications. It supports BDS, GPS, GLONASS, Galileo and QZSS satellite navigation systems. The board adopts triple-frequency RTK technology and can be used for high-precision positioning, navigation and mapping, etc.

Multi-system and Multi-frequency Signal Processing

UB4B0 simultaneously tracks signals from BDS, GPS, GLONASS, Galileo and QZSS and supports tri-band signals from BDS, GPS and Galileo, delivering “instantaneous” RTK initialization and achieving 1-2 cm positioning accuracy. Even in shades or from a long distance, the board still obtains RTK positioning results quickly and reliably

Nebulas-II GNSS SoC

UB4B0M is based on Unicore’ Nebulas-II s multi-system, multi-core, high precision SoC. The SoC supports 432 channels, includes a built-in high performance ADC, an anti-interference unit, two 600MHz ARM processors and two precision floating-point processing units, providing powerful GNSS signal processing capability. capabilities.

Adaptive Anti-interference

Due to a powerful Nebulas-II chip and its high linearity, wide dynamic RF front-end design UB4B0 can effectively suppress narrow band and single-tone radio interference in the GNSS signals. Thus, the customers obtain accurate positioning results even in complex electromagnetic environments.

Rich set of interfaces

UB4B0 is also equipped with interfaces of serial port, USB port, Ethernet port, 1PPS, external clock, CAN and odometer, which can satisfy the needs of various applications. UB4B0 onboard LAN ports can support high-speed output of large amount of data and multiple data streams. It also supports network protocols of TCP / IP, FTP, NTRIP and HTTP.
