Re: [Orekit Users] Adding a Constant Thrust Maneuver while propagating.

Hi,

Hi Pau,


I am propagating from a time A to a time B, and checking for events.
When one event is triggered, a ConstantThrustManeuver is computed and added to the propagator (with a small offset with respect to the current propagation epoch).

The propagator seems not to take into account the constant thrust maneuver in the follow-up propagation.

I have done the same but with a ThirdBodyAttraction (added based on an event trigger), and it does take it into account for the rest of the propagation.

I know that this topic was tackle in May by John Reilly and Evan Ward, we have followed the recommendation to use ConstantThrustManeuver to solve it, but it looks like it does not.
Could anybody help?

Try to add the events detectors embedded with the maneuver by yourself
into the propagator when you add the maneuvers.
The propagator loops over all force models to gather the force model
specific detectors at propagation start, but not afterwards, so if
you add the maneuver after maneuver start, it will never be triggered.

best regards,
Luc


Many thanks in advance,

Pau
