摘要

Complex electromagnetic environment may cause the spacecraft navigation system failures. The influences on the failures of platform inertial navigation system (PINS) and strapdown navigation system (SINS) are analyzed by building typical models of failures and their conditions. Aiming at the influence of navigation failures, the zero-order holding, the linear interpolation and spline interpolation are applied to recover the navigation system. Furthermore, the design and constitute about the simulation system of navigation recovery are discussed. Then these three recovery methods are tested and verified one by one through the simulation. The features of the three recovery methods are evaluated in brief.
