Implementation of GPS twin antennas real-time yaw angle correction system based on MCU

Based on the Crescent Vector single-frequency and single-system testing OEM board with external GPS twin antennas to achieve real-time attitude determination. Take aerial photogrammetry for example, built a GPS twin antennas real-time yaw angle correction system based on MUC. The System acquires data through the OEM board, and real-time control the DC motor by the MCU to real-time achieve the correction of the yaw angle in aerial photography operations.The experimental results shows that the system has high stability and fast responsibility, and makes GPS attitude determination has some reference value In aerial photogrammetry or other engineering application.
