Application of POS in Photogrammetry

POS (Position Orientation System) attitude measurement mainly uses inertial measurement unit (IMU) to sense the acceleration of aircraft or other carriers, and obtains information such as the speed and attitude (such as position or rotation angle) of the carrier through integration and other operations. Therefore, the application of POS in photogrammetry is to obtain the high-precision external orientation elements of each photo by measuring attitude parameters, and cooperate with differential GPS positioning technology to obtain the high-precision external orientation elements of each photo.
