SMART-1 osculating orbit up to 21 December 2003


Date: 22 December 2003
Satellite: SMART-1

In this diagram the osculating orbits at launch (GTO) and at different times are plotted. The large orbit, marked 'final', is the one we expect to achieve at the end of the radiation belt escape (pericentre larger than 20 000 km) in about two weeks time.

From the start, the electric propulsion system has managed to increase the semi-major axis of the orbit by 8500 km, increasing the perigee altitude from the original 656 km to 9158 km and the orbital period by 6 hours and 23 minutes, from the initial 10 hours 41 minutes, to 17 hours 4 minutes.
