Remote Binding System of Initial Parameters of User Terminal on Relay Satellite Arrow

Abstract

The invention discloses a relay satellite rocket-borne user terminal initial parameter remote binding system, and provides a remote binding system with high reliability and good maintainability. The system disclosed by the invention is realized through the following technical schemes: transmitting initial parameter information from portal binding equipment to back-end optical transmission equipment through a cable in an Ethernet signal form of a serial port data flow based on TCP / IP, converting the serial port data flow of the initial parameter information based on the TCP / IP into a self-adaptive Ethernet signal suitable for optical fiber transmission, and converting the self-adaptive Ethernet signal into an optical signal to transmit to the front-end optical transmission equipment, and outputting the optical signal to a serial port server through an internet access, converting the serial port data flow based on the TCP / IP into a RS422 signal capable of being identified by the relay satellite rocket-borne user terminal, wherein the RS422 signal performs data interaction with the remote relay satellite rocket-borne user terminal through a 422 bus, and the relay satellite rocket-borne user terminal initial parameter binding software binds the initial parameter information.

Description

technical field [0001] The invention relates to a space-based measurement and control system in the field of aerospace measurement and control, and relates to a system for remotely binding initial parameters of a relay satellite rocket-borne user terminal. Background technique [0002] The relay satellite rocket-borne user terminal is used in the space-based measurement and control mission of the rocket. It has been widely used in the field of aerospace measurement and control due to its high coverage, multi-target measurement and control, and high-speed data relay. The beam pointing control of the relay satellite rocket-borne user terminal is the key to realizing space-based measurement and control. It can make the phased array antenna of the relay satellite rocket-borne user terminal align with the relay satellite in real time to complete the rocket-relay satellite-ground Station data transmission. Beam pointing control not only depends on information such as the real-tim...

Problems solved by technology

For some user terminals that only have the function of backward data transmission, this method needs to increase the forward receiving channel, which not only increases the size, heat consumption and cost of the terminal, but also greatly increases the cost of manpower and material resources.

[0008] poor security

Since the low-temperature refueling period before rocket launch is a relatively dangerous period, if the operator binds the initial parameters on the launch tower during this period, there is bound to be a certain degree of danger
