LEO satellite orbit determination using GNSS Range measurements with Iono corrections

1

Hi Forum,

I am trying to perform satellite orbit determination (with batch least squares) using OneWayRange measurement obtained from the satellite GNSS receiver (Pseudorange data). I would also like to use a modifier along with the measurements to correct for the Ionosphere delay (especially interested in GlobalIonosphereMapModel).

I can’t seem to find a modifier to use along with the OneWayRange which models ionospheric delay. Would BaseRangeIonosphericDelayModifier help? Any help/leads here would be appreciated.

Thanks in advance!

Hi @gowtham

That’s because there is no ionospheric modifier for OneWayGNSSRange or OneWayGNSSPhase.
If you are interested, we can add it.

Could you open an issue in our Gitlab repository?
