Embodiment Construction

[0023] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The satellite ground control system for intelligent terminals mainly involves the construction of ground measurement and control stations, servers and the development of clients. figure 1 The framework of the system is described in detail as follows:

[0025] (1) The communication between the ground and the satellite, including the reception of satellite telemetry data and the upload of command signals, is carried out by the ground station. The ground station sends the satellite downlink remote sensing data to the server, and the server performs post-processing including distribution to each client. The ground station can decide that the instruction signal uploaded to the satellite comes from the server or is input by the ground station technician, so as to avoid the uncertainty and danger brought by the server failure or attack.

Abstract

The invention discloses a satellite ground control system facing an intelligent terminal and relates to the satellite ground control communication technology field. The system comprises a ground control station, a server and the intelligent terminal. The measurement and control resource of a ground measurement and control station is abstracted into a network resource and then the resource is stored in the server. The server manages information interaction between a satellite and ground. A communication chain is accessed to a satellite transit switching ground measurement and control station. When the server has a fault, a ground instruction is uploaded to the satellite. Ground personnel can especially access a fault-free ground measurement and control station when the ground measurement and control station has the fault. The opportunity of accessing the plurality of ground stations is provided for ground working personnel. The ground working personnel can use the system to control thesatellite through the intelligent terminal anytime and anywhere and can effectively extend communication time with the satellite, and communication reliability is increased.

Description

technical field [0001] The invention discloses an intelligent terminal-oriented satellite ground control system, which belongs to the technical field of communication related to satellite ground control. Background technique [0002] With the development of my country's aerospace technology, the number of satellites in orbit in my country continues to increase, and the burden on ground measurement and control stations will also increase. It is imperative to automate and unmanned ground stations. Ground measurement and control tasks are becoming more and more complicated. Traditional measurement and control methods require measurement and control personnel to be stationed at the ground station to monitor and control satellites, which causes a waste of human resources. Therefore, it is urgent to propose a new measurement and control method that allows technicians to perform measurement and control operations anytime and anywhere. Satellites in orbit often need to exchange a la...
