Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a ground simulation test system and method for secondary discharge of a polar-orbit satellite bus power cable. Background technique [0002] The instantaneous orbit plane where the polar orbiting satellite is located and the sun always maintain a fixed orientation, which can make the time of the place where the satellite passes by basically the same, and the satellite remote sensing detection data has long-term comparability. Because the inclination angle of this kind of satellite orbit is close to 90°, the satellite almost passes through the poles, so it is called "near polar sun synchronous orbit satellite", or polar orbit satellite for short. [0003] The safety and reliability of the satellite energy system is related to the function and life of the satellite. With the continuous emergence of new technologies and new demands for satellites, the requirements for the satel...
