Autonomous Orbit Control: A New Approach in LEO Satellites
Today, in order to reduce costs, the use of small satellites in LEO orbit has been considered and byincrease of observation missions in this orbit, which requires high orbital precision satellites,orbital control of LEO satellites beside attitude control has been especially important. Recent researches have tried toincrease system’s accuracy and on the other hand, reduce costsmore than before by offering autonomous orbit control system. This system hasreduced human intervention in the ground stationby maintaining all or some of satellite orbital elements via satellite itselfand thus has eliminated need of multiple ground stations; also in addition to costreduction andaccuracy increase, it adds abilities to space missions that did not exist before. This researchwill analysis approaches of using autonomous orbit control by expressing features of this system and reviewing theoretical and practical researches in this regard.
