Embodiment 1

[0050] like Figure 1~5 As shown, the deep space communication system suitable for the Phobos exploration mission provided by this embodiment includes a probe 1, a Mars polar satellite 2, a sun-orbiting constellation, a synchronous orbiting constellation and an earth ground station 5; the detection The satellite 1 revolves around Phobos 100 in its quasi-synchronous orbit, the Mars polar satellite 2 revolves around Mars 200 in its polar orbit, and the orbiting constellation includes at least Three sun-orbiting satellites 3 that revolve around the sun 300 degrees in orbit around the sun and are arranged at equal intervals around the sun. Geosynchronous satellites 4 arranged at intervals, wherein the revolution period of the Mars polar satellite 2 is twice the revolution period of the Phobos 100, and the revolution orbit around the sun is located between the earth revolution orbit and the Mars revolution orbit; The initial condition of the relative motion between the probe 1 and...

Abstract

The invention relates to the technical field of deep space exploration, and discloses a deep space communication system suitable for a phobos detection task. On one hand, a Mars polar satellite running on a special polar orbit is arranged on the Mars side, obstacles between the detector and the Mars polar satellite are always prevented from appearing to block decimetric wave communication. The purpose of uninterrupted full period of the decimetric wave communication link from the phobos to the Mars is achieved; on the other hand, at least three revolution satellites around the sun are used asinter-planet relay satellites, the purpose that the laser wave communication link between the planets is not interrupted in the whole period can be achieved; and at least three geosynchronous satellites are used as satellite-ground relay satellites, so that the purpose of uninterrupted full period of the satellite-ground Ku wave communication link can be achieved, the purpose of uninterrupted fullperiod of the complete communication link from the phobos to the ground is finally achieved, and the phobos detection task is ensured not to be affected by communication interruption.

Description

technical field [0001] The invention belongs to the technical field of deep space exploration, and in particular relates to a deep space communication system suitable for Phobos exploration missions. Background technique [0002] Since the first artificial satellite was launched on October 4, 1957, human beings have never stopped their curiosity to explore the entire solar system. So far, more than 160 probes have been sent into deep space to explore the solar system. Even so, only a very small part of the solar system has been explored, and there are many planets, asteroids, dwarf planets, and planetary satellites (such as Phobos, Europa, Callisto, and Titan, etc.) waiting to be explored. [0003] Phobos (Phobos) is the closest natural satellite to Mars. Its remarkable irregular shape and extremely small size are very rare among the natural satellites of planets in the solar system. Phobos has been tidally locked by Mars, so that one side of Phobos always faces Mars. It i...
