| Abstract: | The Simulation Data Source of Platform Inertial Navigation System(PINS) seif-calibration is investigated. By thorough analysis of the Simulation requirements,this paper concludes and summarizes the demand of the simulation data source,and gives the kinetic model which used to produce the data of calibration and simulation. This model not only reflects the error but also avoids the character of the complex control and dynamics,describes the platform case movement to inertial coordinate which is got by solving the differential equation numerically,and gives the output of the accelerometer and the gimbals tangle by solving the algebraic equation. At the typical track of the platform movement, this paper exams the result compared with the academic data,and it indicates that the accuracy on the basis of this simulation which is designed according to the model meets the demand of the self-calibration algorithm. |
