How to apply center of mass correction 3D-vector to OneWayGNSSRange

Dear all,
do you have any suggestion on how to apply the center of mass correction 3D-vector (defined with respect to the satellite reference frame of the receiver spacecraft) to OneWayGNSSRange measurements?

I was thinking to subtract the center of mass correction 3D-vector from the phase center offset vector (constructed as difference between Antenna Reference Point coordinates in satellite reference frame which have Nadir pointing Z-axis and the PCO obtained from ANTEX file) and then use this new 3D-vector to build the OnBoardAntennaOneWayGNSSRangeModifier that at this point will have the antenna phase center correction with respect to the center of mass in the satellite reference frame.

Not sure this is correct. Please could let me know if you have any advice on this?

Many thanks.

Best Regards

This is the correct way to handle phase center offset.
What is done internally is we add back this vector to the center of mass in order to recover the center of phase.

Dear Luc,
thanks for the confirmation. Then I will proceed like this.
