Unicore UB4B0M is a compact RTK board particularly suitable for high precision positioning and navigation. Based on a proprietary Nebulas-II GNSS System-on-a-Chip (SoC), the board delivers low power consumption, millimeter-level carrier phase observations, centimeter-level RTK positioning and supports multi-path mitigation.
Multi-system and Multi-frequency Signal Processing
UB4B0M 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’s Nebulas-II 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.
Thanks to powerful Nebulas-II chip and high linearity, wide dynamic RF front-end design,UB4B0M 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.
Integrated MEMS Navigation
The UB4B0M integrates 6-axis on-board MEMS chip and U-Fusion INS algorithm, resulting in optimized continuity and reliability of accurate heading and positioning output in tough environments such as city canyons, tunnels and overpasses. The board also supports odometer inputs to provide better navigation and positioning performance.
