Description

technical field [0001] The invention belongs to the technical field of aerospace integrated electronics, and in particular relates to a method and device for constructing an integrated electronic system of a spacecraft. Background technique [0002] The traditional electronic system design scheme of spacecraft platform generally adopts a clear-cut subsystem division method, and disperses the electronic system or equipment in such as power supply, digital control, measurement and control, attitude control, propulsion, thermal control, etc. according to the large functional classification. in multiple subsystems. Due to the low functional density, the weight, power consumption and volume of the whole device are large, and the launch cost is high. The sub-systems are independent, the products developed are various, the development cost is high, and the hardware resources are difficult to coordinate and utilize. Moreover, the generalization degree of the equipment is extremely...

AI Technical Summary

Problems solved by technology

However, due to the improvement of the functional integration of the integrated electronic system, the coupling with other subsystems of the whole device is relatively high, so its design iteration process is extremely complicated and long, and it often does not have advantages in the development cycle, and it affects the whole body. A requirement change may lead to repetition of the entire system development work

Therefore, only improving the functional integration without solving the customization problem cannot meet the requirements of rapid development and cannot meet the needs of the rapid development of my country's aerospace industry
