Modeling and Simulation to Improve Precision of Navigation for Space Aircraft Based on Time Compensation

In pervasive computing, the computer is no longer a single computing device, but an information device with the embedded processor, memory, communication module and various sensors together. This paper puts forward an algorithm to improve precision of navigation for space aircraft based on time compensation. The algorithm involves two-body movement time to correct the oblateness perturbation flying time, and then, improve the precision of navigation. On this basis, taking the advantage of pervasive computing in space aircraft application field, we involve pervasive computing technology into oblateness perturbation correction calculation. It provides the guarantee to precision of navigation for space aircraft, and enhances the auto-adaptability of space aircraft in complex space environment.
