UM980 All-constellation Multi-frequency High Precision RTK GNSS receiver.
UM980 is Unicore’s new-generation proprietary high-precision RTK positioning module based on the Nebulas IV SoC which integrates RF, baseband and high-precision algorithm. The module supports GPS L1C/A/L1C/L2P(Y)/L2C/L5, BDS B1I/B2I/B3I/B1C/B2a/B2b, GLONASS G1/G2/G3, Galileo E1/E5a/E5b/E6, QZSS L1C/A/L1C/L2C/L5, NavIC L5 and SBAS L1C/A. 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. Relying on the excellent performance, UM980 is well suited for high-precision navigation and positioning applications such as precision agriculture, surveying and mapping and so on.
Many new geodetic receivers based on the UM980, for example Sfaira One, NetBOX2, Stonex S900 and more.
