In order to solve the problems of the re-entry process of hypersonic velocity aircraft by using the standard trajectory method. Article gives a Gauss pseudo-spectral method to solve the re-entry problem of hypersonic velocity aircraft. The guidance combines the Gauss Pseudo-spectral Method and the Rolling-time Control Method. For the Gauss Pseudo-spectral Method which based on the integration idea that includes the vertical and the lateral side. And the integration includes All-trajectory integration also. By using the Rolling-time Control method, the guidance could realize the open-loop orders. As the result of the simulation, the data shows that after combine the two methods of Gauss Pseudo-spectral and the Rolling-time Control in hypersonic aircraft guidance control, the aircraft achieve a satisfactory result in re-entry trajectory.
