Abstract

A multi-code-rate multi-channel multi-system measurement and control system of a microsatellite comprises a transmit-receive antenna, a USB responder, a spread spectrum responder, an antenna integration USB responder, an antenna integration spread spectrum responder, a microwave network and a comprehensive electronic computer. The comprehensive electronic computer is respectively in communication connection with the USB responder, the spread spectrum responder, the antenna integration USB responder and the antenna integration spread spectrum responder, the USB responder and the spread spectrum responder are in communication connection with the transmit-receive antenna through the microwave network, and the antenna integration USB responder and the antenna integration spread spectrum responder each comprises an integrated measurement and control antenna. The multi-code-rate multi-channel multi-system measurement and control system has the advantages that research cost of a spacecraft is reduced, overall reliability of the tiny spacecraft is improved, the antenna and the responder are integrated, the weight is low and power consumption is low.

Description

technical field [0001] The invention relates to a low power consumption and light-weight micro-satellite ground communication technology, in particular to a micro-satellite multi-code-rate multi-channel multi-system measurement and control system. Background technique [0002] When a spacecraft works in space, it needs the ground to perform remote control, telemetry, and ranging. To accomplish the above work, the spacecraft should be equipped with corresponding systems. In the existing large-scale earth satellite measurement and control technology, the measurement and control of the spacecraft adopts a fixed code rate, and the measurement and control mode is fixed, which is a mature large-scale measurement and control single machine. That is, the spacecraft measurement and control subsystem works with a fixed telemetry code rate, and does not perform data transmission and control. [0003] With the development of aerospace technology, the miniaturization, light weight and ...
