GEOSTATIONNARY LEOP OF A SPACEBUS4000 FROM ALCATEL WITH SEA LAUNCH: FLIGHT DYNAMICS ASPECTS OF THE MISSION ANALYSIS AND OPERATIONS

摘要

A satellite based on a spacebus4000 platform from Alcatel was launched with Sea Launch on August 2006. As it was the first operations for CNES with this launcher, specific Mission Analysis studies were performed including constraints of the mission (interferences, collision, cost, duration, and robustness). The LEOP was then realized differently due to an unexpected injection. Flight Dynamics computed a new strategy in real time with operational means to reduce LEOP duration without overcost. The total duration of the mission was reduced of three days, thanks to strategy choices made during transfer phase.
