Abstract:

The operation principle of POS (Position and Orientation System) is firstly described. Furthermore, problems need to be noted such as eccentricity component measurement, initialization of POS device, accuracy of data control and construction of base station are analyzed. Solutions and preventive measures are proposed in line with the requirements of practical aerial photography. The POS system has been used and tested successfully in several practices. 

Key words: POS, operation principle, application, IMU, DGPS
