Abstract

The invention provides a magnetic torquer signal processing method and system of satellite attitude and orbit control comprehensive test equipment. The method comprises the following steps: a magnetic moment signal resolving step: converting collected magnetic torquer driving current into real-time magnetic moment; a local geomagnetic field determination step: determining the local geomagnetic field intensity according to the real-time position; a magnetic control moment resolving step: resolving a magnetic control moment according to the local geomagnetic field intensity and the real-time magnetic moment information; and a step of adding the magnetic control torque to the dynamic model: establishing an attitude dynamic model, and superposing the magnetic control torque to the attitude dynamic model. The method is suitable for signal processing requirements of magnetic torquer for different satellite attitude and orbit control subsystems, so that the universality of signal processing of the magnetic torquer of satellite attitude and orbit control comprehensive test equipment is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic torquer signal processing, in particular to a magnetic torquer signal processing method and system for satellite attitude and orbit control comprehensive test equipment. Background technique [0002] The general comprehensive test equipment for satellite attitude and orbit control is a generalized equipment to meet the various stages of testing of different types of attitude and orbit control subsystems. The magnetic torquer is mainly used for flywheel unloading and emergency use, and is an indispensable actuator for low-orbit long-life satellites. The specifications and quantities of magnetic torquers used by different models are different, and the requirements for ground test equipment are different. Different models develop and put into production special ground equipment according to their own needs, which often causes a huge waste of resources and affects the efficiency of model development...
