Communication satellite simulator and general telemetry and telecontrol stream data transmission method

Abstract

The invention discloses a communication satellite simulator and a general telemetry and telecontrol stream data transmission method. The communication satellite simulator comprises a main thread module and a measurement and control interface module, wherein the main thread module is mainly responsible for coordination work of the modules, the measurement and control interface module is responsible for simulation of a telecontrol subsystem, transmission of telemetry data and receiving of a telecontrol command, and the main thread module coordinates with the measurement and control interface module to achieve simulation of the satellite telemetry and telecontrol data processing procedure and simulation of the telecontrol subsystem. The communication satellite simulator and the general telemetry and telecontrol stream data transmission method have the advantages that the measurement and control interface module is responsible for external interaction of all telemetry and telecontrol data streams, and therefore high cohesion and low coupling of transmission of the telemetry and telecontrol data streams are guaranteed; the transmission method of the telemetry and telecontrol data streams is easy to modify; no other parts inside the satellite simulator contain pre-coded telecontrol data which are sensitive information than the measurement and control interface module, and therefore safety of the telecontrol data is guaranteed.

Description

technical field [0001] The invention relates to a communication satellite simulator and a general telemetry and remote control data stream transmission method, belonging to the technical field of communication satellite simulation. Background technique [0002] In the field of communication satellites, satellite simulators, as an important supporting product of communication satellites, are playing an increasingly important role. At present, among the domestically developed communication satellites, there are mainly three types of satellite simulator application requirements: the measurement and control docking simulator used to represent the satellite measurement and control technology status for satellite-ground measurement and control docking before satellite launch; Satellite flight simulators for satellite mission rehearsals; satellite operations simulators for user training during satellite development and in-orbit life. [0003] In the next few years, there will be d...

Problems solved by technology

Information transmission and data communication are carried out between the satellite simulator modules through the interface protocol. The traditional satellite simulator communication protocol design does not consider universality, so every time a new model of simulator interface protocol is developed, it needs to be redesigned and changed, resulting in the content of the simulator Repeated construction, low development efficiency, and difficult quality control are not conducive to the generalization of future simulators and the needs of users for mass production
