Abstract

The invention provides a measurement and control communication antenna configuration system of a Mars probe, and relates to the technical field of satellite antennae. The method comprises the steps of configuration of a measurement and control receiving antenna and configuration of a measurement and control transmitting antenna, wherein the configuration of the measurement and control receiving antenna comprises a first low-gain receiving antenna, a second low-gain receiving antenna and a high-gain receiving antenna; and the configuration of the measurement and control transmitting antenna comprises a first low-gain transmitting antenna, a second low-gain transmitting antenna, a middle-gain transmitting antenna and a high-gain transmitting antenna. According to the invention, the problem of ground measurement and control communication of the Mars probe in the whole process from active section launching, device-rocket separation, ground fire transfer section, attitude adjustment, deep space maneuvering to ring fire communication and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of satellite antennas, in particular to a Mars probe measurement and control communication antenna configuration system. Background technique [0002] The maximum distance between the domestic space probe and the ground is around 400,000 kilometers for lunar-ground communication, while the maximum distance for the Mars probe is 400 million kilometers. During the entire process of the Mars exploration mission, the distance between the vehicle and the ground is constantly changing, from the short distance of the active section to the maximum distance of 400 million kilometers, and the signal propagation space loss varies widely. Coverage, but also to meet the normal communication and emergency communication requirements under long-distance conditions. [0003] The invention patent with the publication number CN109103599B discloses a satellite antenna positioning structure and a satellite antenna, including a ...
