Abstract
Official abstract text for this publication.
A method for stationing a satellite, comprises: determining a predefined trajectory for stationing of the satellite based on a model of movement of the satellite; determining parameters of the predefined control law of approximation of the trajectory and by minimizing impact on the control law of deviation from a trajectory followed by the satellite using parameters of the control law; determining a state vector of the satellite; determining a deviation between the state vector and the predefined trajectory; determining Lagrange multipliers based on a current state vector of the satellite, on a deviation between current state vector and predefined trajectory and on parameters of the predefined control law; determining parameters of the current control law of the engines based on the Lagrange multipliers and by derivation of a parameter representative of an effect of engines on the real trajectory; and controlling engines based on parameters of the current control law.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for stationing a satellite, characterized in that it comprises: a first step of determining a predefined trajectory used for said stationing of said satellite based on a model of movement of said satellite; a second step of determining parameters of a predefined control law of approximation of said predefined trajectory and minimizing an impact of said predefined control law on a deviation from a real trajectory followed by said satellite us…
