DA Simulator Design of Inertial Platform in Self-calibration

Research and design to data acquisition process of inertial platform in self-calibration has been carried on in this paper. After overall module design of simulator, based on the analyses of error source during calibration, error models of various components of platform system are introduced and accelerometer and AS (angle sensor) readings generator simulation algorithm are designed in according to the principle of actual system. VC++ is used to simulate the system. As a result, the simulation system is consisted with actual system basically, and simulation data can replace actual data as test data of calibration algorithm, which reduces the cost greatly.
