BDS/GPS/GLONASS/Galileo/QZSS system  RTK/INS  module

Module

BDS/GPS/GLONASS/Galileo/QZSS
Full-system, full-frequency RTK/INS integrated navigation module

UM981 is a new generation of BDS, GPS, GLONASS, Galileo, QZSS full-system, full-frequency RTK/INS integrated navigation module independently developed by Hexinxingtong. It is based on the new generation of radio frequency baseband and high-precision algorithm integrated GNSS independently developed by Hexinxingtong. SoC chip—NebulasIV design. It can simultaneously track all system and frequency points such as BDS, GPS, GLONASS, Galileo, QZSS, NavIC, SBAS, etc. Integrated high-speed floating-point processor and RTK dedicated co-processor to achieve 100 Hz positioning result output. Integrating the onboard MEMS chip and U-Fusion combined navigation algorithm, it effectively solves the problem of interruption of positioning results due to loss of satellite signal lock, and can provide continuous high-quality positioning in complex environments such as buildings, tunnels, viaducts, and tree shades. Positioning results. For high-precision navigation and positioning fields such as surveying, mapping, precision agriculture, etc.
