Modelling of the positioning procedure starting from primary orbit for the geostationary satellite Symphonie
Abstract
For the computation of the minimum fuel rendezvous of Symphonie with its geostationary target point, a modified gradient projection method was used. The corresponding cost function and mission constraints are modelled. Based on this model a highly flexible software package was developed which can handle a wide range of problems. In the Symphonie project it was used for the mission analysis and after launch in two operational modes: one as a subroutine of a stochastic optimization program to compute the apogee impulse and the other within a second program to determine the orbit corrections after the apogee impulse was executed.
