Energy distribution method of GEO satellite under evening launch window during transfer orbit

Abstract

An energy distribution method of a GEO satellite under an evening launch window during a transfer orbit relates to the field of geosynchronous orbit satellite energy distribution. The method comprises: step 1, switching on a communication cabin in the satellite to replace a heater; step 2, at reaching the moment t1 before the first orbit change of the satellite, raising the temperature value of the communication cabin replacing the heater to A2; step 3, at reaching the moment t2 before the first orbit change, reducing the temperature value to A3; step 4, raising the temperature value to A4 until the first orbit change of the satellite is completed; step 5, at reaching the moment t3 before the second orbit change of the satellite, raising the temperature value to A5; step 6, reducing the temperature value to A6 at reaching the moment t4 before the first orbit change; and step 7, raising the temperature value to A7 until the second orbit change of the satellite is completed. The method is applicable to the geosynchronous orbit satellite under the evening launch window, the satellite reasonably distributes the energy of the whole satellite during the transfer orbit, and the energy security for various missions of the satellite during the transfer orbit is ensured.

Description

technical field [0001] The invention relates to the field of geosynchronous orbit satellite energy distribution, in particular to a transfer orbit energy distribution method under the evening launch window of GEO satellites. Background technique [0002] After the GEO satellite is launched into the transfer orbit, the satellite relies on its own power to complete the orbit change and fixed point. The orbit that the satellite passes from the satellite-rocket separation point to the synchronous orbit working point is called the transfer orbit. The main tasks of the GEO satellite transfer orbit are to complete satellite sun capture, earth capture, engine ignition, pyrotechnics unlocking and extraterrestrial components deployment, etc. During the period, keep the satellite attitude, energy and temperature control within the normal working range. [0003] During the orbit transfer period of a GEO satellite, the satellite generally undergoes multiple orbit changes. During the orbi...

AI Technical Summary

Problems solved by technology

[0003] During the orbit transfer period of a GEO satellite, the satellite generally undergoes multiple orbit changes. During the orbit change period, the satellite attitude changes greatly, and the solar panels of the satellite are greatly affected by the sunlight. At present, there is no reasonable allocation of energy for the entire star. method, it cannot guarantee that the temperature of the whole star meets the working requirements of the products on the star during the transfer orbit, it cannot guarantee that the discharge depth of the battery pack does not exceed the specified threshold, and it cannot guarantee the temperature of the whole star and energy security.
