Full-configuration real-time simulation test method based on double-satellite hardware in loop

Abstract

The invention discloses a full-configuration real-time simulation test method based on double-satellite hardware in a loop. The method comprises the following steps: step 1, two sets of satellites respectively carry real-time simulation test systems; step 2, data communication mechanisms of the two sets of test systems perform communication interaction by using a fixed-period mutual transmission mode, one set of test system is used as a time sequence main control end, the other set of test system is used as a controlled end, and the controlled end receives a rising edge or a falling edge of amain control end signal to complete time correction work in a triggering mode; and step 3, a software time supplementing mode is used to ensure the time consistency of the track data, so that the timebetween the two sets of test systems is synchronized. According to the invention, the communication protocol interaction can be carried out through two modes of RS422 serial port communication or UDPnetwork port communication under an engineering constraint condition, and the formation test task of the double-satellite formation is completed through a time synchronization method.

Description

technical field [0001] The invention relates to the technical field of spacecraft engineering, in particular to a full-configuration real-time simulation test method based on dual-satellite hardware-in-the-loop, and more specifically, to a debugging method for a joint test platform of a hardware-in-the-loop real-time simulation system for two sets of satellite attitude and orbit control. Background technique [0002] Satellite attitude and orbit control system, as one of the most complex subsystems among many satellite subsystems, plays a very critical role in satellite control. At present, the simulation test work in the research and development stage of the satellite attitude and orbit control system is completed through the real-time satellite hardware-in-the-loop fully configured real-time simulation system to verify the integrity of the satellite attitude and orbit control performance and the reliability and safety of the flight mission. . Hardware-in-the-loop is an im...
