Abstract:

To meet the requirements of multi-fold continuous-coverage of space targets, a design method of even-fold continuous-coverage constellation based on the large angle detection range is proposed. Firstly, the ring detection area is determined by the large angle detection range, and a design method of the street of coverage is proposed. Then, a method of even-fold continuous-coverage constellation design for space targets is proposed based on the method of street of coverage splicing. The proposed constellation design method has two advantages. First, it introduces a constrained parameter optimization method for the constellation design method based on street of coverage splicing, which can quickly design an even-fold continuous-coverage constellations with as few satellites as possible. Second, the sensor detection area is selected as a ring, which can expand the application range of the proposed constellation design method. When the sensor points to the sky, the designed constellation can achieve even-fold continuous-coverage of high, medium and low orbit space targets. When the sensor points to the ground, the proposed method is also suitable for even-fold continuous-coverage of ground targets at any latitude. Simulation results show that the proposed constellation design method is simple and effective, and can quickly achieve even-fold continuous-coverage of space or ground targets with fewer satellites.
