The invention provides a polarity test method based on a structural satellite and electrical satellitecombined propulsion system and a system thereof, and the method comprises the steps: 1, connecting an upstream pipeline of a structural satellite thruster with a gas source, and installing a device for detecting the ejection of gas at a nozzle of the thruster; 2, placing an electrical satellite on a two-dimensional turntable, and placing the structural satellite at a preset distance around the two-dimensional turntable; 3, connecting the structural satellite to the electrical satellite through an umbilical cable; and 4, converting the attitude angle of the electrical satellite through the two-dimensional turntable, and performing consistent conversion on the attitude angle of the electrical satellite after a corresponding thruster nozzle on the structural satellite detects that the gas is ejected. The method is suitable for propelling system polarity testing in the synchronous and parallel development process of satellite models including the structural satellite and the electrical satellite, a propelling system real product is only configured in the structural satellite, and an attitude and orbit control system real product is only configured in the electrical satellite; the problem that the propelling system cannot independently verify the polarity of the system on the structural satelliteor the electrical satellite and the interface matching performance with an attitude and orbit control system can be solved.
Description
technical field [0001] The invention relates to the technical field of polarity testing, in particular to a polarity testing method and system based on a combined propulsion system of a structural star and an electrical star. Background technique [0002] The satellite propulsion system mainly cooperates with the attitude and orbit control system to complete tasks such as attitude control, orbit modification, and flywheel unloading. If the polarity of the propulsion subsystem is wrong, it may cause the probe to have no thrust, insufficient thrust, and control attitude reversal. The satellite cannot maintain a specific attitude or Predetermined orbit, in severe cases, the entire mission will fail. [0003] At present, the polarity test method of the propulsion system is mainly aimed at the acquisition device for detecting whether there is jet at the thruster nozzle or the joint polarity test method for a single satellite from the attitude and orbit control system to the propu...
