Research and realization of GPS based attitude determination simulation and verification system

The precision of attitude determination approach is a significant index of GPS based attitude determination. Numbers of attitude determination testing will be needed to test the reliability of the method. However, the particularity and complexity of the actual test make it impossible that testing the veracity of attitude determination method. Therefore, the verification scenario of attitude determination method has been given in this contribution. The simulation of satellites range information has been built by the designation of comprehensive error models, which provide an actual measurement norm. Further more, the movement platform has been built, which solved the problem for checking the calculation impression. Simulation based on traditional attitude determination method has been taken, and the precisions of attitude results has been calculated in all movement states. It is shows that, the simulation and verification platform is reality and availability.
