The report presents a discussion on problems related to orbit transfer of satellites under optimal conditions from a 200 km circular orbit to the 24 hours equatorial orbit. Suitable for this mission there are only such electric propulsion systems, which are able to produce exhaust velocities of about 40000 m/s for a specific power of 0,1 kW/kg, if an optimal payload is requested. After a discussion of the electric propulsion and control systems suitable for such a mission, a comparison is made with a chemical propulsion system, which results in a significant superiority for electric space propulsion, on the other side the transfer time is much longer.
