Single frequency high-precision attitude measurement and orientation module

EMA-AT300 is a low-cost, high-performance, miniaturized directional high-precision board that combines satellite navigation and MEMS sensors. It integrates two independent GNSS receivers and a high-precision positioning and orientation processor, and simultaneously receives two BDS (B1I) and GPS (L1) satellite signals from dual antennas. Using carrier phase differential positioning technology, it achieves real-time high-precision, high stability, and high reliability orientation measurement.
