The invention discloses a whole satellite full-momentum management function test system and method. Specific to satellites in which the large angle momentum interference problem probably exists, existing test equipment is utilized to comprehensively and effectively verify whether the functions of a whole satellite full-momentum management mode are normal and whether the performance of the whole satellite full-momentum management mode reaches the standard in the whole satellite ground test period, and the gap of domestic spacecrafts in test methods for testing functions is filled. The whole satellite full-momentum management function test system and method are successfully applied to whole satellite full-momentum management function verification tests when a radiometer antenna or a scatterometer antenna of a sea satellite separately goes wrong, and pass satellite in-orbit flight whole satellite full-momentum management function test verification. The practice shows that the test method can effectively meet the requirement for whole satellite full-momentum management function ground verification and have certain significance for spacecraft tests with the similar test requirements.
Description
technical field [0001] The invention relates to a test system and a test method, in particular to a test system and a test method for a whole-satellite full-momentum management function, belonging to the field of remote sensing satellite whole-satellite test. Background technique [0002] The technology of modern low-orbit remote sensing earth observation satellites continues to develop, among which microwave remote sensing technology for the earth is one of the new technologies. If the antenna works in a conical scanning mode, since the mass of the rotating part of the antenna is equivalent to 1 / 10 of the mass of the entire star, it will cause a large angular momentum interference to the attitude control of the entire star. The disturbance angular momentum is beyond the control capability of the momentum wheels in the normal mode of the attitude and orbit control subsystem. Therefore, the attitude and orbit control subsystem has designed the whole star full momentum managem...
