Measurement, control and data transmission integrated system for micro-nano satellites

Abstract

The invention provides a measurement, control and data transmission integrated system for micro-nano satellites, which comprises a measurement, control and data transmission integrated module, a processor module and a load module, and is characterized in that the processor module sends satellite telemetry data to the measurement, control and data transmission integrated module and receives telemetry quantity acquisition data of the measurement, control and data transmission integrated module; the load module receives the upper injection data of the measurement, control and data transmission integrated module and returns load data to the measurement, control and data transmission integrated module; the measurement, control and data transmission integrated module comprises a to-the-sky transceiver module and a to-the-ground transceiver module. The independent design of multiple single machines of a traditional satellite measurement and control and data transmission subsystem is replaced,the functions of measurement and control, data transmission, storage and the like are integrated, the functions of measurement and control and data transmission are achieved at the same time throughthe same channel, miniaturization, integration and simplification design of microsatellites is facilitated, the application efficiency of a ground measurement and control network is improved. The method is a future satellite-ground communication development trend.

Description

technical field [0001] The present invention relates to the technical field of micro-nano satellite communication, in particular to a micro-nano-satellite-oriented integrated measurement, control, data transmission system. Background technique [0002] Traditional satellite measurement and control and data transmission belong to two subsystems, which are usually composed of multiple stand-alone units such as measurement and control transponder, transceiver network, data transmission transmitter, solid storage and AOS. In the existing satellites, the receiving and sending rate of measurement and control data transmission is single. In order to meet the margin of the satellite-ground link, the data transmission is usually based on the premise of satisfying the harshest space environment and the lowest ground elevation angle. However, with different space environments and ground elevation angles, the satellite-ground link usually has a large margin, which is not conducive to th...

Problems solved by technology

However, the above-mentioned scheme has the following disadvantages: the above-mentioned scheme only performs transparent forwarding work such as signal radio frequency processing and modulation and demodulation, and does not store data for measurement and control and digital transmission data. The storage of satellites in the prior art requires another stand-alone implementation. Not conducive to the integration of micro-nano satellites

In addition, the above-mentioned scheme does not carry out the channel coding and decoding and framing of the measurement and control digital transmission signal; the above-mentioned scheme uses a separate form of transmitting and receiving for the measurement and control antenna, and a total of four antennas are required for the sky and the ground, which is not conducive to the minimization of the layout and weight of the micro-nano satellite. Lightest; and the above scheme does not mention the data transmission rate of measurement and control digital transmission
