A satellite depends entirely on a GNSS receiver to acquire current time and to synchronize each sub-system. To generate stable current time information and synchronization signal such as PPS(Pulse Per Second), it is very important to maintain a 3D fi

This paper describes an ionospheric model correction for single-frequency GNSS receiver operated in low earth orbit. Various models have been proposed for removing ionospheric time delay, all of which were developed for GNSS receivers operating on th

In this paper, a collision avoidance maneuver frequency for the KOMPSAT-2 and the KOMPSAT-5 is analyzed. For the statistical prediction of the avoidance maneuver frequency, mission orbits, responsive time, accepted collision probabilities, and positi
