The Emulator Software Design For Tracking Telemetry Command And Communication Simulator Of Satellites

The satellites tracking telemetry command and communication simulator is a special emulate equipment which is designed for the on-ground tracking telemetry command and communication system to connected and jointed before the satellites was launched.The simulator is used to verify the on-ground tracking telemetry command and communication system correctness and harmony on interface,information exchange and the tracking telemetry command programs.In all previous Spacecraft missions,the tracking telemetry command and communication simulator acted a very important effect.As our country’s third generation spaceflight tracking telemetry command ship put into commission and would take part into the Shenzhou 7 Spacecraft tracking telemetry command commission,in order to check the function of the tracking telemetry command and communication system of the ship,the Spacecraft tracking telemetry command and communication simulator is a useful method,thus the Spacecraft tracking telemetry command and communication simulator must be developed for new ship.After analyzed the function and specialty of the former Spacecraft tracking telemetry command and communication simulator,this article put forward a designed scheme of a multi-mission and multi-model emulator software for the Spacecraft tracking telemetry command and communication simulator based on MVC design model.The emulator software used MFC application as the base frame,and used the multithreading technology and modular technology to design the database interaction,trajectory emulate,telemetry emulate,remote command execute effect emulate,fly process emulate and malfunction emulate function,etc.This article analyses the function and implement theory of all component modules,and makes deep discussion on the orbit emulator after the Spacecraft changed its orbit and simulator system internal debugging support.The Spacecraft tracking telemetry command and communication simulator emulate software could provide base platform services for other Spacecrafts,Spacecraft and other spacecraft.Its modular design makes it good heritability and expansibility.
