A new 16-position self-calibration method for inertial platform was proposed in view of lack of method which could estimate a lot of error coefficients. Firstly, through analysis of platform structure and installation error, the error model contains 54 error coefficients was derived. Then, impact of frame shaft rotation sequence for observability of system was analyzed. Combined with actual situation of the platform and the error model, a new 16-position scheme for self-calibration was presented. The simulation results show that the calibrating method proposed in this paper can estimate all error coefficients with high accuracy.
Key words： inertial platform; self-calibration; error model; least-square
