I was hoping someone might have encountered this with Survey Pro before.
I keep getting an error message "unable to transform coordinates". I'll set up a new job, collect my date and @ the end of the day do an OPUS solution on a control point. Then I'll import GPS control and the error comes up on any new job I try to start, any thoughts?

Version 4.7 of Survey Pro if that helps

I've had that happen for the following reasons:

I key in the geodetic coordinates for a control point and forget to put the minus sign on the longitude.

I am working outside of the limits of my geoid file. (My current file is 200 miles across so I don't have that happen anymore.)

Occasionally when the unit goes "autonomous" or "float" for a short duration. It usually corrects itself when the GPS gets a "fixed" position.

I hope that helps.
