Happy New Year!

I’ve just tried to equate some fixed stations that have been defined a bit like this;

fix 809 2502023 6021519 594      4 4 12

but I get errors from therion like this;

error -- equate of two fixed stations -- 809@NSpots.NgaruaArea and A1@a.Kairuru.NgaruaArea

These represent gps fixes taken at the same place on various occasions and part of various overland surveys.

At first look it seems like this might be a desired response from Therion.  How can two stations with specified and differing co-ordinates be ‘equal’?

My assumption was that the standard errors give the actual position of the station a degree of uncertainty or ‘fuzzyness’, and that by equating two such stations they would be ‘averaged out’ in a similar way to loop closures or two fixed stations connected by a survey network.  But it seems I might have assumed wrong.

Is it part of therions design to allow equating a number of fixed stations? 

By using alternative syntax or connecting the stations with a dummy survey leg with large std error perhaps?
