An entry guidance algorithm with no-fly zone avoidance for hypersonic glide vehicles is proposed, which makes full use of the differential flatness property of longitudinal plane entry dynamics. The algorithm uses differential flat theory and Gaussian pseudospectral method for discretization to derive analytic longitudinal plane guidance commands in the longitudinal plane, which satisfies path constraints and terminal constraints. Furthermore, considering the influence of the earth curvature, combined with the spherical triangle relationship, a lateral maneuver strategy for avoiding autonomous no-fly zone is designed. This method is simple and convenient for on-line calculation. The simulation results demonstrate that the method preforms well and has great robustness.
