UM980C is Unicore's new-generation proprietary all-constellation, multi-frequency high-precision RTK positioning module, developed based on the GNSS SoC Nebulaslv which integrates RF-baseband and high-precision algorithm. The module supports multiple systems including GPS, BDS, GLONASS, Galileo, QZSS, NavlC, SBAS and L-Band, supports QZSS L6D (CLAS) PPP-RTK solution, and Supports TruePoint REACH Sat L-band-based PPP-AR service. The built-in multi-frequency anti-jamming technology enhances RTK solution on multiple modes and frequencies, which significantly improves RTK initialization speed, measurement accuracy and reliability in challenging environments such as urban canyons and tree shades. UM980C is ideal for surveying and mapping, and precision agriculture.
