Abstract

The invention provides a low-earth-orbit satellite data transmission and relay baseband processing integrated design device and method. The low-earth-orbit satellite data transmission and relay baseband processing integrated design device comprises a filling frame device and the like. The filling frame device and a first cache are located at the left side of a real-time channel scheduling unit and are connected with the real-time channel scheduling unit. A real-time formatting unit is located at the right side of the real-time channel scheduling unit and is connected with the real-time channel scheduling unit. A time delay channel scheduling unit is located at the right side of a second cache and is connected with the second cache. A time delay formatting unit is located at the left side of the time delay channel scheduling unit and is connected with the time delay channel scheduling unit. The design method provided by the invention is reasonable and reliable and is simple in engineering realization and flexible in in-orbit application. The reference and basis for future low-earth-orbit satellite data transmission and relay baseband processing design are provided.

Description

technical field [0001] The invention belongs to the field of satellite data transmission, and in particular relates to an integrated design device and method for low-orbit satellite data transmission and relay baseband processing. Background technique [0002] The low-orbit satellite data transmission subsystem and relay subsystem are loaded on various low-orbit satellites and other spacecraft, and are important components of low-orbit satellites. The main function of the digital transmission subsystem is to multiplex, format, store, encode, scramble, modulate and amplify the data acquired by the satellite payload subsystem to ensure reliable satellite-to-ground transmission of data. Due to the fact that the low-orbit satellites are invisible to the domestic ground station for multiple consecutive circles, the data transmission subsystem receives and records the payload data when working overseas, and when the satellite flies back to the domestic ground station and is visibl...
