  • A satellite is launched into a low-Earth (parking) orbit with an altitude of 222 km and need to be moved into a geosynchronous orbit with an altitude of 38,622 km. Based on this information, perform the following 12 calculations: 222 km + 6378 km = 6600 km 38622 km + 6378 km = 45000 km 1. Determine the semimajor axis of the transfer orbit.
