UM982 Dual Channel RTK GNSS receiver board with USB C and JST

UM982 Dual Channel All-constellation Multi-frequency High Precision GNSS receiver board with USB C and JST connectors. UART, SPI* and I2C* interfaces. Base, dual antenna Rover and dual antenna heading operations.

UM982 is Unicore’s new-generation proprietary high-precision RTK positioning and heading module based on the Nebulas IV SoC which integrates RF, baseband and high-precision algorithm. Its main and secondary antenna inputs can simultaneously track multiple frequencies of all GNSS systems, and the module can perform on-chip RTK positioning and dual-antenna heading calculations. The module supports GPS L1C/A/L2P(Y)/L2C/L5, BDS B1I/B2I/B3I, GLONASS G1/G2, Galileo E1/E5a/E5b and QZSS L1/L2/L5. The built-in multi-frequency anti-jamming technology enhances RTK calculation on multiple modes and frequencies, which significantly improves RTK initialization time, measurement accuracy and reliability in complex environments such as city blocks and tree shades. Featuring the extraordinary positioning performance and reliability, UM982 is a perfect choice for high-precision navigation and positioning applications, such as UAV, autonomous machine and precision agriculture. Board can be used for a Base, Rover or Heading operation mode.
