Looking at the computation of the common parameters in GroundReceiverMeasurement, and in particular transitPV, I found a difference between the implementation without derivatives (in computeCommonParametersWithout) and that with derivatives (in computeCommonParametersWithDerivatives).
Without derivatives, the transitState is computed using SpacecraftState.shiftedBy(dt), and then transitPV are extracted from it. If transitState contains an orbit, the shift is based on Keplerian dynamics.
With derivatives, TimeStampedFieldPVCoordinates are initialized from the input (non-shifted) state, and the transitPV are computed using the TimeStampedFieldPVCoordinates.shiftedBy(dt) method. The shift is based on rectilinear motion with constant acceleration.
This causes the estimated measurement computed using theoreticalEvaluationWithoutDerivatives to slightly differ from that computed with theoreticalEvaluation (w/ derivatives).
I did approve it some times ago (at least at mail verification step), but it still is “pending”, I don’t know if next step is on gitlab administrators or users side.
I just tried, I still get a red banner saying Your account is pending approval from your GitLab administrator and hence blocked. Please contact your GitLab administrator if you think this is an error.
I am using the OAuth via GitLab.com. Should I try to login with my email resetting the password?
Also, I didn’t receive any email saying it was approved or similar.
The MR is here.
About 20 tests on orbit determination fail. Whilst some of them are just a question of adjusting a little bit the tolerances, some are a bit more worrysome.
It could come from the test data, I don’t know, but I’m not sure a proper analysis can be performed before 13.1 unfortunately, which means it would need to wait for later (and not a patch, as it introduces too much numerical differences I would say).
