Abstract

The invention discloses a generalized small space-borne digital transponder terminal platform, which belongs to the technical field of aerospace measurement and control. It includes a radio frequency front-end unit and an intermediate frequency and baseband signal processing unit. The radio frequency front-end unit includes a transceiver distribution network module, a receiving channel module, a transmitting channel module and a local oscillator frequency source module. The intermediate frequency and baseband signal processing unit includes a high-speed analog-to-digital conversion module, a low-speed Analog-to-digital conversion module, digital-to-analog conversion module, signal processing module, configuration and refresh module, clock generation module and communication interface module. The invention is a hardware platform for realizing the function of the measurement and control transponder, which supports multiple measurement and control systems, has the characteristics of generalization, miniaturization, and digitization, and is especially suitable for the requirements of factors such as research and development cycle, volume, power consumption, and cost. In the higher microsatellite system, it is an important improvement to the existing technology.

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 transpon...
