UM4B0 is the smallest high precision positioning and heading module in the world. Based on Nebulas-II SoC, it can track all current visible GNSS satellite signals, including BDS B1/B2/B3, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b and QZSS L1/L2/L5. Its targeted application fields include light-weight robots, GIS, intelligent driving, UAV etc.
The smallest multi-system multi-frequency RTK Module
UM4B0 is the first multi-constellation and multi-frequency RTK SMD module in the world (30x40 mm). With the highest level of integration among the industry, this module contributes to a significant reduction of terminal size.
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.
“UGypsophila” RTK processing technology
Coupled with a high-performance data-sharing capability and simplified operating system within the Nebulas II, UM4B0 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 initialization time of 5 seconds and improved accuracy and reliability.
Nebulas-II GNSS SoC
UM4B0 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.
