Electronic topology architecture for micro-nano satellite

Abstract

The invention relates to an electronic topology architecture suitable for a micro-nano satellite in the field of satellite-borne electronic systems. The electronic topology architecture is composed of a single machine and comprises a processor module A / B, a functional module, a ground spread spectrum measurement and control module, a small S relay measurement and control module, a data protectionmodule, a solid storage and AOS module, a GPS / BD module and a data transmission transmitter. On the aspect of information topology, data management software and attitude and orbit control software are combined for operation, telemetering framing and remote control processing are uniformly processed by an FPGA, two sets of measurement and control redundant links of ground spread spectrum and smallS relay are provided, and data processing and ground transmission functions of a data transmission link are integrated. According to the invention, integration and centralized control of micro-nano satellite electronic information functions are realized, and expansibility and universality are achieved.

Description

technical field [0001] The invention relates to the field of satellite-borne electronic systems, in particular, to the highly integrated and comprehensive electronic topology architecture technology of micro-nano satellites. Background technique [0002] Traditional satellites generally divide the various functions of the satellite into sub-systems, and each sub-system of the satellite is designed one by one, and then they are superimposed. The advantage of this design method is that the satellite can well meet the mission requirements undertaken. The disadvantage is that it takes too much time, manpower and financial resources. The cost of satellites is high and the development cycle is long. [0003] Since the 1980s, with the development of many new technologies and research results, scientific research institutions, aerospace industry groups and colleges and universities in the world's major aerospace countries have carried out related research work on micro-nano satell...

AI Technical Summary

Problems solved by technology

[0004] At present, my country is actively developing its own micro-nano satellites. Obviously, in today's increasingly demanding micro-nano satellites, there are higher requirements for satellite volume, weight, cost, development cycle and performance. Traditional satellite development has exposed more and more drawbacks. It cannot meet the requirements of small size, light weight, low volume cost, short development cycle and high performance of micro-nano satellites

[0005] At present, there is no explanation or report on related technologies similar to the present invention in the field of aerospace, and no similar data at home and abroad have been collected yet.
