Abstract
This study will explain about disturbance potential on LAPAN A1 satellite caused by solar radiation pressure during an extreme geomagnetic storm period. During storm period, satellites 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 time span 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 choose 2003-2013 as 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 storm. However, the results show that the influence of storm was not significant. For the follow up research, we need high resolution data to see the effects of storm more detailed.
