A spaceborne integrated spread spectrum transponder

Abstract

A spaceborne integrated spread spectrum transponder is provided. The communication channel of the satellite and the ground relay satellite is used for receiving the control information and the rangingsignal sent by the ground measurement and control system, and transmitting the telemetry information and the ranging information on the satellite to the ground. The communication channel of the satellite and the ground relay satellite is used for receiving the control information and the ranging signal sent by the ground measurement and control system. The communication channel between the satellite and the space-based relay satellite is used to receive the control information sent by the relay satellite and transmit the telemetry information on the satellite to the relay satellite. The transponder adopts standard external information interface, including relay measurement and control radio frequency signal input interface, relay measurement and control radio frequency signal output interface, ground measurement and control radio frequency input and output interface, power input interface, remote control command input interface, telemetry output interface, remote control PCM output and telemetry PCM input interface. This paper realizes the communication between satellite and ground TT & C system and space-based relay satellite, and realizes the integrated design of two communication systems.

Description

technical field [0001] The invention relates to a product for satellite measurement and control communication, in particular to a product for data communication between a satellite and a ground measurement and control station or a space-based relay satellite. Background technique [0002] The task of the satellite measurement and control system is a system for tracking, measuring, monitoring and controlling the satellite flight orbit, attitude and working status of other subsystems, involving radio navigation, communication, microwave, electronic engineering, etc. In order to accomplish the above tasks, at present, the satellite measurement and control system must communicate with the ground measurement and control system on the one hand, and communicate with the space-based relay satellite on the other hand. The two communication systems use two sets of products. However, the weight and power consumption of the two sets of products are relatively large, and at the same time...

AI Technical Summary

Problems solved by technology

However, the weight and power consumption of the two sets of products are relatively large, and at the same time, the layout, installation and wiring connection of the two sets of products on the satellite structure have brought a burden to the satellite design.

In addition, the development of the two sets of products requires separate considerations of mechanical design, thermal design, and electromagnetic compatibility design. In addition, various environmental tests, such as temperature step tests, aging tests, thermal vacuum tests, etc., can be found in It is pointed out that the two sets of products have brought relatively large manpower, design, material and time costs to satellite development.
