Single-Board satellite borne integrated electronic system

Abstract

The present invention provides a single-Board satellite borne integrated electronic system. The single-Board satellite borne integrated electronic system comprises a refresh arbitration module, a data processing module, a satellite service interface module, a satellite service CPU module and an inter-board connector; the refresh arbitration module is connected with a first external device and a second external device through the inter-board connector so as to receive stored data and telemetry data; the data processing module is connected with a third external device through the inter-board connector so as to receive remote control commands; the satellite service interface module is connected with a fourth external device through the inter-board connector so as to receive satellite service data; and the satellite service CPU module is connected with the refresh arbitration module, the data processing module and the satellite service interface module through the inter-board connector so as to receive satellite service data, remote control commands and telemetry data. The system of the present invention has the advantages of high expansibility and high integration.

Description

Technical field [0001] The invention relates to the technical field of on-board electronics, in particular to a single-board on-board integrated electronic system. Background technique [0002] The satellite platform is generally composed of modules such as telemetry, AOS, remote control, satellite services, attitude control, energy, and thermal control. Each module generally implements its module function in the form of an independent stand-alone computer. According to the traditional satellite development plan, the satellite is composed of various sub-systems; each sub-system is developed by various professional aerospace institutes and installed in the entire satellite as an independent stand-alone unit; the satellite's final assembly and integration testing work is in charge of the satellite overall unit. Obviously, for this kind of satellite composed of individual sub-systems, the development cycle is prolonged, the weight of the satellite is increased, and the power consump...

Problems solved by technology

However, it has not really achieved high integration and low power consumption; the existence of a unified backplane for the integrated electronic system (stand-alone) makes the function expansion weak. Once functional modules need to be added, the backplane needs to be redesigned
