Solar radiation pressure on LAPAN A1 satellite due to extreme geomagnetic storm

Abstract

This study will explain about disturbance potential on the LAPAN A1 satellite caused by solar radiation pressure during an intense geomagnetic storm period. During the storm period, satellite orbital parameter is affected due to the changing of solar radiation pressure, atmospheric chemical composition, and atmospheric density. Therefore, we analyze solar radiation pressure in the period of 11-years to compare the effect at minimum phase, maximum phase, and storm period. One of the most massive geomagnetic storms happened in 2003, so we chose 2003-2013 as the data period. To calculate solar radiation pressure on satellite, it needs data of daily total solar flux from Solar Radiation and Climate Experiment satellite (SORCE). Data processing is done by using python. Then we had calculated Solar Radiation Pressure values during a year to see the effects of the storm. However, the results show that the influence of the storm was not significant. For the follow-up research, we need high-resolution data to see the effects of the storm in more detail.
