Abstract

The invention provides a micro-type satellite multi-code-rate multi-channel multi-system measurement and control system which comprises a two-channel receiving and transmitting measurement and control antenna A, a microwave network, a USB measurement and control responder A, a spread spectrum measurement and control responder A, a two-channel receiving and transmitting measurement and control antenna B, a USB measurement and control responder B, a spread spectrum measurement and control responder B and a comprehensive electronic computer. The two-channel receiving and transmitting measurement and control antenna A is respectively connected with the USB measurement and control responder A and the spread spectrum measurement and control responder A through the microwave network. The USB measurement and control responder A and the spread spectrum measurement and control responder A are respectively connected to the comprehensive electronic computer. The two-channel receiving and transmitting measurement and control antenna B is respectively connected with the USB measurement and control responder B and the spread spectrum measurement and control responder B. The USB measurement and control responder B and the spread spectrum measurement and control responder B are respectively connected to the comprehensive electronic computer. According to the micro-type satellite multi-code-rate multi-channel multi-system measurement and control system, the good effect is provided for a micro-type satellite for completing near-earth orbit flying and communication control.

Description

Technical field [0001] The invention relates to a low-power, lightweight micro-satellite-to-ground communication technology, in particular to a system design technology that can be used for ground remote control, telemetry, and distance measurement electronic equipment in different orbits near the ground. Background technique [0002] When a spacecraft is working in space, it needs remote control, telemetry, and ranging on the ground. To complete the above work, the spacecraft should be equipped with corresponding systems. In the existing large-scale satellite measurement and control technology on the earth, the measurement and control of the spacecraft adopts a fixed bit rate, and the measurement and control mode is fixed, which is a mature large-scale single-machine measurement and control. That is, the spacecraft measurement and control sub-system works with a fixed telemetry code rate, and does not transmit and control digital data. [0003] With the development of aerospace ...
