The inclined orbit operation and services of Koreasat 1

Koreasat 1 consumed much of its on-board fuel during orbit acquisition. Therefore, its lifetime was reduced to 4.4 years. The inclined orbit operation scheme is being established to extend its lifetime. In this paper, an inclined orbit operation scheme is established and its effects on existing services are analyzed. The spacecraft's residual lifetime in the inclined orbit is estimated by fuel analysis.
