Satellite clock offset

Good afternoon. Sorry for my bad english. Thank you very much for such a great tool as orekit, and a special thank you for python wrapper. I have a question. I’m trying to estimate the pv of the satellite using slr. Everything is being clarified, but I also need to estimate the satellite clock offset together with pv. I do this using Sattelite = ObservableSatellite(0).getClockOffsetDriver(). setSelected(True) before adding measurements to estimator. However, this parameter is not displayed in the covariance matrix or in getMeasurmentsParametersDrivers (False).getDrivers(). But it has a 0 value, although the selected flag is equal to True.
Maybe I’m doing something wrong.

Hi @Suslov46

Welcome to the Orekit forum.

This a strange behavior. What you’ve done looks good. Are you using a batch least squares or a Kalman Filter to estimate the PV and the clock offset?
Can you provide an executable code or a sample of code in order to see if the error is elsewhere?

Best regards,

thank you very much for wasting your time on my problem. I use a batch least squares

Thank you for the example. I will take the time to see if I found an error.
