The application of precise point positioning in the IMU/GPS-supported photogrammetry

摘要

We systematically analyzed the accuracy of Precise Point Positioning (PPP) combined with the investigation of the IMU/GPS-supported aerial area, and compared the PPP with the differential global position system (DGPS). The precision of PPP in mapping was checked by sampling areas. Our data illustrates that the accuracy of PPP in medium or small scale of IMU/GPS-supported aerial photography is almost same as DGPS, which satisfies the requirements of specifications.
