Vacuum thermal test method of mass production satellite constellation system

Abstract

The invention provides a vacuum thermal test method of a mass production satellite constellation system. A plurality of satellites are put into space environment simulation equipment simultaneously, thermal balance satellites and thermal vacuum satellites are selected correspondingly, and thermal control states of the thermal balance satellites are worse than that of the thermal vacuum satellites;a thermal balance test is carried out on the thermal balance satellites; during the process of the thermal balance test, equipments on the thermal balance satellite is powered up according to an in-orbit established working mode, and external thermal flow is applied to the surfaces of the thermal balance satellites according to external thermal flow design parameters; the external thermal flow ofthe thermal balance satellites is corrected in real time by simulating the influence of the mutual occlusion of the satellites on the external thermal flow of the thermal balance satellites; and during the process of the thermal balance test, the equipment on the thermal vacuum satellites is powered up according to an in-obit established working mode, and no external thermal flow is applied. After the thermal balance test is completed, the high and low temperature range of a thermal vacuum test of the satellite system is determined according to thermal balance test results, and the thermal vacuum test of the tested satellite system is carried out.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a vacuum heat test method for batch production of satellite constellation systems. Background technique [0002] With the continuous development of aerospace technology, the functional density of spacecraft is getting higher and higher. At present, the miniaturization and batch development and production capacity of spacecraft have been realized. A satellite constellation is a collection of several or more satellites that are launched into orbit and can work normally, have similar functions, and are combined in a certain way. For the completion of tasks such as global communication, navigation and environmental monitoring, any place on the earth must be covered by satellites at any time. To achieve this, it is not enough to use one satellite, and multiple satellites are needed in a certain way. Form a satellite network to realize the above functions. At this stage, miniaturi...
