Abstract

The invention discloses a fully autonomous lunar surface navigation and data communication method based on spherical satellites. Selecting a circular orbit around the moon as the navigation satellite orbit can effectively cover the lunar surface and ensure that any point on the lunar surface can receive effective data at any time. The navigation satellite signal, under the condition of knowing the initial state of the spherical satellite, can obtain the orbit forecast value in a long period of time. In addition, the inversion of dynamic model parameters through inter-satellite ranging can obtain high-precision dynamic models, and realize high-precision prediction of constellation ephemeris to support long-term fully autonomous operation of constellations. In addition, the space position of the lunar user can be obtained by measuring the distance between the lunar user and the multiple spherical satellites observed by it, which can provide accurate target position and speed for lunar activities and implement efficient data communication services, which can realize The navigation and positioning of any point on the lunar surface and the data transmission between any two points on the lunar surface can well meet the mission requirements of manned lunar landing activities.

Description

technical field [0001] The invention relates to the technical field of lunar satellite navigation and communication, in particular to a method for fully autonomous lunar surface navigation and data communication based on spherical satellites. Background technique [0002] The moon is rich in mineral resources, many of which are rare elements on the earth, which are of great significance to economic activities on the earth and will make important contributions to the sustainable development of human society. The lunar debris is rich in rare gas elements, among which helium-3 is a fuel for controllable nuclear fusion, which has more advantages than deuterium and tritium. At the same time, the low-gravity environment of the moon also provides superior conditions for carrying out scientific experiments. When humans carry out activities on the lunar surface, they need the support of many infrastructure conditions. Among them, lunar surface navigation and data communication are o...
