Description

technical field [0001] The invention relates to the technical field of satellite on-board electronics, in particular to micro-satellite integrated electronic technology, in particular to a modularized micro-satellite platform integrated electronic system. Background technique [0002] Integrated electronic systems first originated in the aviation industry. With the improvement of the fire control capability of fighter jets, the original distributed fire control system is developing towards the integrated direction of distributed centralized control, forming a system based on the bus and using the fire control computer as the management center to integrate the previously independent functions on the aircraft The subsystems are integrated together to form a computer network with distributed and centralized control of functions, which realizes the interactive synthesis of information and functions. [0003] With the continuous maturity of aviation integrated electronic system ...
