Unicore's new-generation proprietary high-precision RTK positioning module. The module supports all currently available constellations and frequencies. It features a 50Hz RTK data update rate, and supports PPP, including E6 HAS and BDS B2b. With its excellent performance, UM980 is well-suited for high-precision surveying-grade applications, including surveying and mapping, precision agriculture, and deformation monitoring.
Based on Unicore's proprietary GNSS SoC NebulasIV that integrates RF, baseband and high-precision algorithm
All-constellation multi-frequency RTK engine and advanced RTK technology
Instant RTK initialization technology
60 dB narrowband interference suppression and interference detection
Heading2 technology to provide orientation information
STANDALONE single-station high-precision positioning technology
Supports B2b-PPP, E6-HAS and QZSS L6E (MADOCA) PPP
