Description
Dual-antenna high-precision OEM GNSS receiver module provides heading determination (as well as pitch/roll) combined with precise RTK positioning. It tracks, depending on options, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, BeiDou B1/B2, NavIC(IRNSS) L5 and SBAS L1 signals. On-board loosely-coupled GNSS/INS integration algorithm helps to fuse data from GNSS measurement unit with MEMS-based IMU sensor. The raw measurement data are available for user’s secondary processing, as well as API functions for own developments, thus, using our modules, users are free to create an effective solution for each specific application.
