A Status Report on KASI Prediction Center (KAS)

The Korea Astronomy and Space Science Institute (KASI) has been providing a supplementary Consolidated Prediction Format (CPF) for Science and Technology Satellite (STSAT)-2C as one of ILRS prediction centers since April 7, 2014. The abbreviation in CPFs by KASI is KAS. As satellite laser ranging (SLR) observations can be used for orbit determination (OD) for STSAT2C, an attempt to make enhanced CPFs from SLR-based OD was accomplished. In this study, we report an operation status and prediction procedure on KASI prediction center. For verification of CPFs generation strategy, test periods are prepared first and their results are investigated. Next, regular periods are started with CPFs generation if new SLR observations are available. The details of satellite orbit predictions procedure are described and the history of KAS CPFs for STSAT-2C generation is summarized. We will prepare better strategy for quality assessment of KAS CPFs and continuously try to generate confirmed CPFs for more SLR tracking for STSAT2C.
