Embodiment Construction
[0083] The present invention is described in detail below in conjunction with accompanying drawing:
[0084] Such as figure 1 As shown, the present invention provides a kind of engineering design method of navigation satellite constellation, comprises the following steps:
[0085] Step 1: Determine the altitude of the satellite orbit;
[0086] The higher the orbital altitude of the satellite, the better the ground coverage performance, and at the same time it can avoid the influence of the Earth's radiation belt, but the increase in the orbital altitude will put forward higher requirements for the signal transmission power and the launch capability of the launch vehicle. Therefore, the choice of orbital height is a result of full balance.
[0087] This step is as follows figure 2 shown, including the following steps:
[0088] S1.1. Screen candidate orbits according to the influence of the space radiation environment, and obtain the first set of candidate orbits that meet ...
