You're being very vague about what you are doing. This makes it
unreasonable for anyone to try to help you, and it makes your post not
that useful for others.
You left out:
- what geometry type are you using
- (related) how are you storing height
- how do you store the data and what does it look like when you get it
back to gsis. Include 'ogrinfo' output of a sample point and if all
your data is protected by NDA go out and measure a geodetic control
point in a public place. (You should be doing that anyway to check
your system.)
- how are you dealing with ARP to mark offset
+ and also APC to ARP
- are you doing differential GNSS and what is the datum of the
reference system

You did not describe everything in your email!

You probably need a consultant then!
