A comprehensive baseband processing system for satellite-to-ground measurement, operation and control of small satellites in medium and low orbits

Abstract

The invention discloses an integrated baseband processing system for satellite-ground monitoring, operation and control of small satellites in medium and low orbits. The system includes: an integrated baseband processing subsystem based on a ZYNQ chip and a configuration monitoring and display module deployed on a host computer; the integrated baseband The processing subsystem is used to dynamically reconstruct different modulation and demodulation algorithms according to the parameter configuration commands of the configuration monitoring and display module, and decode and demodulate the telemetry data downloaded by the small satellite according to the corresponding adjustment and demodulation algorithms before sending. To the configuration monitoring display module, the command data generated or transmitted by the configuration monitoring display module is encoded and modulated and sent to the small satellite; the configuration monitoring display module is used to configure the parameters of the integrated baseband processing subsystem and send commands , which is used to store and display the downlink telemetry data received by the integrated baseband processing subsystem, and also to communicate with the ground control center.

Description

technical field [0001] The invention relates to the technical field of satellite measurement and control communication, in particular to a comprehensive baseband processing system for satellite-ground measurement, operation and control of small satellites in medium and low orbits. Background technique [0002] Medium and low-orbit satellites have significant features such as wide coverage and low cost, and achieve global coverage by networking with multiple satellites. In recent years, my country has vigorously promoted the development of civil and commercial aerospace in medium and low orbits. The number of small satellites for civil and commercial use in medium and low orbits has increased sharply. Medium and low orbit satellites are fast and have short orbital periods. The equipment requirements are relatively high, and the ground measurement and control communication equipment needs to develop in the direction of miniaturization, portability and movement at any time, vers...

Problems solved by technology

[0003] However, at present, the integrated baseband processing equipment for ground station measurement, operation and control has a single function, which cannot be reused in different satellite-to-ground measurement and control communication tasks, and the communication link capacity is low, consuming a lot of resources. Therefore, there is an urgent need for a universal, scalable Configurable, reconfigurable, expandable, comprehensive baseband processing system for satellite-ground measurement, operation and control applicable to different communication methods between satellites and ground
