Thread-topic: multiple thrust calibration

Hi all,

I need to perform a single orbit determination which covers several maneuvers. I want to calibrate the thrust of each maneuver separately but I cannot find the way to do it with the ConstantThrustManeuver class.

The thrust parameterDriver name is declared “final static” so the estimator considers that all maneuvers have the same thrust. It eventually creates several rawDrivers that have the same value (even if the maneuvers initially have different thrust levels). Am I right or did I miss something ?

I bypassed this problem by re-defining another maneuver class taking a ConstantThrustManeuver and a maneuver name as attributes and implementing AbstractForceModel but I don’t find it satisfactory. Is there a better way to do it ?

Thank you in advance for your answer,

Quentin
