Deep space communication system suitable for phobos detection task

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...

Problems solved by technology

[0006] In order to solve the problems faced by the existing Phobos exploration missions, such as the inability to maintain full-cycle continuous communication, large antenna caliber, high transmission power, and the need for global multi-point layout of ground equipment, which lead to susceptibility to geopolitical influence and limited inter-planetary communication rates, The purpose of the present invention is to provide a novel deep space communication system suitable for Phobos detection missions
