Planetary detection measurement and control communication system

Abstract

The invention provides a planetary exploration measurement and control communication system, which is used for ultra-remote communication scenes including Mars and Jumur exploration, and comprises two power amplifiers which are configured to be respectively provided with a high transmission power and a low transmission power, the low transmission power is used for near-field communication and protecting ground deep space measurement and control system equipment, the high transmission power is used for far-field communication, and the high transmission power is used for near-field communication and protecting ground deep space measurement and control system equipment. Enough emission EIRP is ensured; four pairs of antennas, wherein each pair of antennas is configured to be capable of transmitting and receiving signals at the same time; the high-isolation duplexer is configured to ensure that each antenna can be used for transmitting and receiving signals at the same time; wherein the four antennas are selected, and the output powers of the two power amplifiers are selected, so that measurement and control communication in various distance ranges is respectively carried out.

Description

technical field [0001] The invention relates to the technical field of deep space exploration, in particular to a planetary exploration measurement and control communication system. Background technique [0002] The measurement and control communication system is used in deep space exploration satellites such as asteroid exploration and Mars exploration. It is a transmission channel for remote control instructions, telemetry information and load detection data between the satellite and the ground. Remote control, orbit determination and load data transmission. [0003] The existing measurement and control communication system schemes for deep space exploration spacecraft have some shortcomings, such as: [0004] There are three deficiencies in the staged multi-bit rate adaptive measurement and control system of a Mars exploration deep space spacecraft: [0005] One is that there are a large number of antennas, and a total of 6 antennas are required, including 4 low-gain (w...

Problems solved by technology

[0010] The purpose of the present invention is to provide a planetary detection, measurement and control communication system to solve the problem that existing solutions cannot achieve miniaturization, low cost and difficult star layout due to the large number of antennas and power amplifiers

[0011] The purpose of the present invention is also to provide a planetary detection, measurement and control communication system to solve the problem that some medium and high-gain antennas cannot be used for reception in the existing solutions, the antenna gain is low so that it cannot support ultra-long-distance communication, and the communication between the transmission channel and the high-power amplifier cannot be realized. Issues such as the inability to form omnidirectional beam coverage during cross-connection backup and emergency communications
