Abstract
The first LAPAN’s experimental star sensor has onboard on LAPAN-A3/LAPAN-IPB microsatellite that successfully launch on June, 6 2016. The second LAPAN’s experimental star sensor called STELLAR has scheduled to be onboard on LAPAN-A4 satellite. In orbit test of first star sensor provide conclusions. One of the conclusion is the radiation in space has an impact on star sensor performance. Many hot pixels or hotspots appear on CCD sensor temporarily that it causes a failure of star identification since the hotspots are fake stars. In order to solve this problem, an enhancement of algorithm is conducted. The enhancement aims to ignore the fake stars to proceed as stars candidate. This method selects a cloud pixel as star candidate and proceed only clouds pixel. The algorithm was tested and give more reliable result of star identification.
