UB9A0

All-constellation All-frequency GNSS High Precision Board

UB9A0 is Unicore's new-generation proprietary high-precision RTK positioning board based on NebulasIV SoC which integrates RF, baseband and high-precision algorithm, supporting GPS, BDS, GLONASS, Galileo, QZSS, NavIC and SBAS. The board provides millimeter-level carrier-phase observations and centimeter-level RTK positioning output, and supports advanced multi-path mitigation and low elevation angle tracking. UB9A0 is compatible with mainstream GNSS OEM boards on the market and  provides UART, Ethernet, and other interfaces to meet the needs of users in different  applications such as surveying and mapping, CORS stations, portable base stations,  earthquake monitoring and global monitoring stations.
