Summary and Conclusions

Currently, KOMPSAT-5 is in a detailed design phase. KASI is in charge of developing of the AOPOD system, which includes a dual frequency GPS receiver and a laser retro reflector. A dual frequency GPS receiver will be used for generation of POD data and occultation science data. For processing the occultation data, KASI is developing KROPS. The first version of KROPS will be released by the end of year 2008.

Since KOMPSAT-5 has only one ground station, KOMPSAT-5 contacts the ground station twice a day. The occultation data from KOMPSAT-5 will be released only twice a day. The limitation of S-band telemetry downlink rate of KOMPSAT-5 restricts the amount of occultation data, which can be downloaded to the ground station. Current estimation of maximum amount of occultation data is 30 MB/day. In addition to this limitation, due to the location of the occultation antennas on the KOMPSAT-5, multi-path problems and field of view limitations are expected.
