Problems solved by technology

In this scheme, the communication between the satellite and the space-based measurement and control network is realized during the satellite’s in-orbit operation, but it is still unable to communicate with the space-based measurement and control network during the mission phases of satellite launch and orbit, and it cannot meet the needs of manned spacecraft in the entire mission phase. Communication requirements with space-based measurement and control network

Abstract

The invention relates to a space-base measurement and control communication system of a manned spacecraft. The system comprises a narrow beam relay sub-system, a wide beam relay sub-system and a central control sub-system. The narrow beam relay sub-system comprises a narrow beam relay terminal, a narrow beam relay antenna and a high-speed data treatment device. The wide beam relay sub-system comprises a wide beam relay terminal and two wide beam relay antennas. The central control sub-system receives and sends forward and backward signals through the narrow beam relay sub-system and the wide beam relay sub-system respectively. The narrow beam relay sub-system is in link connection with a space-base measurement and control network according to the normal running posture and rail running state of the manned spacecraft, and therefore the communication between the space-based measurement and control network and the manned spacecraft is realized. When the posture of the manned spacecraft greatly changes, all-directional coverage of the communication system of the manned spacecraft is realized by the wide beam relay sub-system.

Description

technical field [0001] The invention relates to a space-based measurement and control communication system, in particular to a space-based measurement and control communication system for a manned spacecraft. Background technique [0002] In the manned spaceflight mission, the application of the space-based measurement and control network composed of the relay satellite system has improved the coverage of the measurement and control network, effectively ensuring the smooth execution of various manned spacecraft on-orbit test tasks. As manned space launch missions become more frequent, the technical requirements for high-speed data transmission and target measurement and control of measurement and control networks are higher, and space-based measurement and control networks are more widely used in manned spaceflight missions. [0003] At present, in order to meet the needs of TT&C and data transmission, space-based TT&C systems of manned spacecraft are usually equipped with S...
