The MRG1000 module is a compact and high-precision positioning and orientation module developed based on high-performance chips. It supports the reception of all constellation and all frequency point GNSS signals including the new signal system of Beidou-3. The MRG1000 module supports various differential modes such as RTK, DGNSS, ground-based augmentation, and PPP, and can provide positioning services with centimeter-level, decimeter-level, and meter-level accuracy as well as high-precision orientation services. This module is equipped with an anti-interference design and supports combined navigation with inertial devices. It can be widely applied in professional markets such as surveying and mapping, deformation monitoring, precision agriculture, mechanical control, intelligent transportation, and unmanned aircraft.
