UB4B0 Image

The UB4B0 is a Multi-Band High Precision GNSS OEM Board from Unicore Communications. It supports triple-frequency Real Time Kinematics (RTK) technology for geodetic surveying engineering survey, deformation monitoring, mechanical control, meteorological monitoring, precision agriculture, and continuous operation reference station (CORS) applications. 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 navigation signal processing. It supports GNSS signals from BDS B1/B2/B3, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, and QZSS L1/L2/L5 constellations. This GNSS module has a cold start of less than 40 s, a hot start of less than 10 s, and a positioning updating rate of 20 ns. It requires a DC supply of 3.3 V and has a power consumption of 2.8 W.

The UB4B0 supports advanced multi-path mitigation and low angle tracking and can be controlled via UART, RS-232, Ethernet, LAN, and USB interfaces. It is available in a module that measures 100 x 60 x 11.4 mm.
