Method for improving orbit-transferring safety of inclined orbit satellite

Abstract

The invention relates to a method for improving the orbit-transferring safety of an inclined orbit satellite, wherein the problem of energy-source shortage of the inclined orbit satellite in the period of orbit-transferring motorization under the condition of high solar angles is solved through the reasonable adjustment of flight events by considering the condition of solar altitude angles in the designing process of a flight program, and meanwhile, flight-control operation can be simplified. The discharging time of a storage battery in the period of orbit-transferring ignition can be shortened by designing the flight program according to the method, so that the load power in the power-supplying period of the storage battery is reduced, therefore the discharging depth of the storage battery is reduced, the energy-source safety of the satellite is ensured, and a launch window is not limited by solar illumination angles.

Description

technical field [0001] The invention relates to a method for improving the safety of orbit change of an inclined orbit satellite, which can ensure the safety of energy and thermal control during satellite orbit change, and is mainly used during flight control of inclined orbit satellites. Background technique [0002] Generally, the geosynchronous orbit satellite has a low sun altitude angle after launch into orbit, and the sun illumination angle (the angle between the sun's rays and the projection of the sun's rays on the satellite's orbital plane) is small during orbit change ignition, which meets the power supply demand of the satellite. Therefore, the flight program design during the orbit change generally does not need to consider the problem of energy shortage. The common flight program design method during the orbit change is: according to the orbit change strategy and the tracking arc section, arrange the earth capture sequentially and establish the earth pointing att...

AI Technical Summary

Problems solved by technology

According to calculations, in the case of high sun angles, if the common flight program design method for medium and high orbit satellites is adopted, the discharge depth of the battery will exceed the design value, which will affect the safety of satellite power supply.

If the design of the satellite is changed, such as increasing the battery capacity, or changing the launch window of the satellite, such as only choosing to launch in the season with a small solar altitude angle, it may increase the development cost of the satellite, and even affect the completion of the satellite launch task. Net satellites may not be able to avoid launching during high sun seasons
