Vasily, I don’t understand the reason of such solution.

If you know gps coordinate of a station, you may use fix for it. And than equate those fixed stations. Way you need to add third virtual station with GPS coordinates?

Are you trying to create a survey with only one station with GPS coordinates?

Hi, Bruce

Fixed@cave is a nonexistent station (nor defined nor fixed). Therion is right with warning but it is exactly what I need. I'm try to define station in upper namespace for link to it from other places. It is worked proper but throw a warning...

After the experiments I found a workaround. This code removes warning but it a bit verbose and not obvious...

survey cave
  centerline
    data nosurvey from to
    Fixed Fixed@some.path.at.cave
    equate Fixed Fixed@some.path.at.cave
  endcenterline
endsurvey

So, to clarify my understanding of your example.
Fixed@cave = is for example a gps coordinate, defined elsewhere with a fix statement.
Fixed@some.path.at.cave = is a survey station that is defined in a survey, for that same location.
Fixed@other.path.at.cave = is another survey station that is defined in, perhaps, some other survey.
All three stations represent exactly the same physical location.
