Subject: RE: RTK with MODOT CORS, Paradyme and Lefebure NTRIP app.



Cedar Rapids, Iowa
If I had to guess, I'd bet it's the Paradyme. That receiver has a quirk where if it gets data from a base that is close to the location of a previously used base, it will act as if the new base is at that previous base location. Basically it adds an offset of an unknown amount.

I know DigiFarm has gone to substantial effort to do some things on the back side of their system to make the Paradyme not do this. To my knowledge, none of the DOT RTNs have done anything specific to the Paradyme. If you can recreate the issue in one specific location, it might be worth talking to DigiFarm for more details or to try their system to see if the issue goes away.

Edit: You want the VRS_RTCM31 data stream. The Paradyme prefers RTCM v3.1 data.
