Abstract: This paper simply introduces the theory and method of the boresight misalignment calibration of integrated GPS/IMU,and then a corresponding function model is established.Based on the test flight data,this paper not only validates the validity and the feasibility of the boresight misalignment model,but also analyses the accuracy of direct georeferencing by using the model mentioned above.
