IMPROVING LEO SATELLITE COMMUNICATION COVERAGE AREA BY USING LEO-GEO CROSS-LINK

This paper presents a proposal for a data relay technique, which utilizes an existing Geo-stationary Orbit (GEO) communication satellite as a data relay satellite, in cooperation with Low Earth Orbit (LEO) satellite. The proposed scheme can increase the communication availability with the remote sensing LEO satellite. Moreover, the proposed system improves both the communication coverage area of the LEO satellite and its scanning availability in the real time. This improvement is a real need in the remote sensing applications.
