Anybody have a spreadsheet for calculating horizontal/vertical accuracy for RTK/VRS that they are willing to share??ÿ Using Microsoft Excel.
Thanks

I'm not sure I follow - RTK vectors typically have positional precisions associated with them, accessible during post-processing. Are you looking for those, or something else?
What data fields will you be outputting from your system to use as input for that spreadsheet? You do realize that only precision info is available for output, not accuracy.?ÿ
That's ok I'll just calculate it, thanks anyway 😮 ?ÿ

@landman, ah cool. Please share that here when you're done. I'd love to learn how to calculate accuracy from RTK precision 😉
OK, the question was "Anyone have a spreadsheet for computing positional accuracies per NSSDA validation specs, as outlined in Part 3 of the FGDC Standards?"
I used to have some precision/accuracy spreadsheets for FGDC error circle calcs (estimated from error ellipses) and TS sets, but I don't think I have the NSSDA computations in spreadsheet format. One of my coworkers might. I will check.
Do you mean a priori error estimates for a least squares computation??ÿ?ÿ
@landman
Duncan Parnell also has videos on how to do this with OPUS and VRS. If you have these recorded training available to you, they have the excel spreadsheets and xml files for download.

@firestix
I don't have the videos or spreadsheets but I would love to get them if available
Thanks
