Sigh, not my day.?ÿ I took the 10 mm as a sideways error, but if it is the radial error at some confidence, the sideways error would be 7 mm, so was o...

Yes, I mis-spoke. ?ÿ

I suppose the bearing and distance are to the "point" floating in air rather than on the pipe.

My RINEX files created by TEQC have newline characters hex 0D 0A after each time the column gets too wide, rather than after all data from one satelli...

It is likely the heading sensor mentioned is in addition to GPS and at a minimum needs to be rotated into agreement with the boat heading, and possibl...

We had a thread recently where a file wasn't being accepted and it turned out the way it was generated under Win10 it used 16-bit characters. Changing...

But only until the next fool decides on a different spot. (fool = either a licensed deed staker or a scarcely supervised crew, holding a different st...

For me. they all come up in an NGS search as "Outside NGS publication area" with no data. How did you see them? As of about 2000 when Geocaching took...

Ouch. I find it hard enough at 42 latitude.

The spec linked earlier calls for 60?ø spacing, so NE-SW etc. isn't quite correct.?ÿ I didn't notice an angle tolerance but would guess a very few deg...

Just draw a thin triangle. Sideways error = Distance * tangent(azimuth error)?ÿ?ÿ where both errors are at the same confidence level standard error=...

Is it just the camera angle??ÿ Those lines don't look 60?ø apart.

Just in case anyone cares, here's a definition for MCS.

Some states have acquiescence statutes.?ÿ In Iowa if a definite line is treated as the boundary by both adjoiners for 10 years, in a dispute a court m...

How long before somebody pincushions the Point of Beginning for Martian coordinates??ÿ Or have they already?

8450 ft isn't too bad if you aren't working (i.e. hiking uphill).?ÿ I did fine hiking the Grand Canyon south rim, constant 7000, but was barely functi...

Compare the azimuth accuracy of GNSS.?ÿ If you measure two points a quarter mile apart with a sideways uncertainty of 0.05 ft that's 8 arc seconds. So...

There are two solar methods, hour angle and altitude. Each has it's own factors that limit accuracy. My impression is that the limiting accuracy is a ...
