Description

technical field [0001] The invention relates to the technical field of aerospace measurement and control, in particular to a generalized small spaceborne digital transponder terminal platform. Background technique [0002] Traditional space-borne measurement and control transponders are generally implemented with pure analog devices. Analog transponders are mature in technology and high in reliability, and are still widely used in complex large-scale satellite systems. However, its single function, poor design flexibility and poor hardware inheritance, and its large volume, weight, and high power consumption make it difficult to meet the application requirements of microsatellites. Contents of the invention [0003] In view of this, the present invention proposes a generalized small space-borne digital transponder terminal platform, which can meet the needs of miniaturization, low power consumption, low cost, and short development cycle for measurement and control tran...
