Description
Dual antenna high precision OEM GNSS module provides heading determination (as well as pitch) combined with precise RTK and PPP positioning. The module supports the following satellite systems and signals: GPS L1, L2, L5, GLONASS L1, L2, Galileo E1, E5a, E5b, BeiDou B1, B2, NavIC(IRNSS) L5, S-band and SBAS L1. The loosely-coupled GNSS+INS integration algorithm helps to fuse data from GNSS unit with data from MEMS-based IMU sensor that makes it ideal solution for systems requiring continuous positioning. The raw GNSS measurements are available for user’s secondary processing as well as API functions for his/her developments. Thus, using NTL104 OEM GNSS module, users are free to create an effective solution for each specific application.
