This article systematically summarizes and elaborates the GPS/INS supported photogrammetry basic theory, key technology and sources of error,combined with Tongchuan (1:500,1:1000,1:2000)、Huangling (1:2000) and Rongcheng (1:1000) measurement of the production of experimental data, focusing on compares and analyzes the GPS / INS supported photogrammetry comprehensive accuracy、regular aerial triangulation accuracy and GPS / INS direct targeting accuracy,discusses the feasibility of the GPS/INS supported photogrammetry In large scale mapping, and finally to take Pingshuosurveying area as an example, formed a complete Implementation process of the GPS/INS supported photogrammetry. This mainly includes the following: 1. Analysis and organize the GPS/INS supported photogrammetry related data in domestic and international, combined with the experimental data and production practice, and systematically elaborates the GPS/INS supported photogrammetry basic theory、the definition of the coordinate system of Inertial navigation technology and photogrammetry、the GPS/INS supported photogrammetry key technology and sources of error. 2. Posed the GPS/INS supported photogrammetry in the airborne GPS positioning accuracy requirements, combined with the domestic situation, the layout plan of the base station. The experiment results show the relationship of the DGPS accuracy and base stations and aircraft distance.On this basis, the optimal base-station layout plan and reconciliation，DGPS computing solution. 3. Applicated Tongchuan (1:500,1:1000,1:2000), Huangling (1:2000) and Rongcheng (1:1000) data, comparison and analysis the regular aerial triangulation accuracy (Bundle adjustment)、the GPS / INS direct targeting accuracy and the GPS/ INS supported photogrammetry comprehensive accuracy，Finally, conclusion. 4. Finally to carry out the GPS/INS supported photogrammetry full project implementation process in Pingshuo test area, and formed a complete set of feasible implementation plans.At the same time using different calibration field data, analysis of different values on the accuracy.
