The three meter rods are a flat out pain. I contacted NEDO in Germany and they manufacture a 'guitar case' sort of metal box for them, but they were ...

One clarification to my above post; the 6.5mm difference I still have floating about is between my 8 section computed GRS80 ellipsoid distance the NGS...

I wasn't sure about the "AR" code for azimuths, but it does seem to be calculating angles correctly.The "BP" and "FP" codes are correct on the backsig...
First thing I noticed is, you are traversing with azimuths and not angle right.Would that make a difference?And, your first BS check looks a little fu...
Sounds like a geometric/gravimetric correction issue.Are your coordinates transverse or lambert?Is there a significant deflection of the vertical in y...
If I understand your issue, why not use the backsight as a measurement code "M".Something like this for example;M 1-2-1 00-00-03 90-00-00 100.000M 1-2...

How about trying a sokkia aps 41?It has a height adjustment with a lock screw (an actual screw).
For years I printed out the raw files and typed everything into the .dat file by hand.I'm pretty satisfied with the converter now.Could it be the file...
For example, this adjustment appears to have passed rather well, however, the error factors should all be 1.000 (i.e. unity) in an ideal adjustment.Ti...
