PPK point extractor software

(Jurijs Ješkins) #42

I am developing this software on my Mac, so I don’t have any RTKlib here installed. I try to maintain, that software is multiplatformal. What exactly do you need?

(Tobias Dahms) #43

That is a good idea. I don’t need anything, I just wanted to discuss. But now I understand that it is not possible.

(Jurijs Ješkins) #44

It is possible, but it will be available only on Windows. I will see, what I can do.

Thank you, but if you don’t use it you don’t need to implement it. I have my own Windows script (I also like to learn programming) but I work with Python - less beautiful but I think it is simpler to use for a lot of different things.
But I really like your programm, reminds me on R Shiny - very beautiful and powerful too.

Help me understand the difference with corrected_alt (18m) and elevation (30m). Should it be antenna height + elevation for corrected_alt? Dataset collected with 2 Reach RS base and rover.

Other than that. Awesome software !

It depends, whether you made corrections for antenna in RTKlib or not. I still don’t know why you have such a difference. corrected_alt is just averaged values from processed POS file.

In my sample data I have a difference too - between values, measured in SINGLE mode and processed values. The difference is ~4 meters, which is ok. I see, that your points in CSV file are already FIX. How did you got FIX in the field? You were using 2 Reach units? Or you were connected to the NTRIP caster?

It also depends on how you process your data. Please, describe how you measure and what are you using.

Used 2 reach rs+ units base over known point, manually imputed the coordinates in to the base. RTK with the rover. Processed with Emlid’s RTKPOST, in the “options” - “positions” corrected the antenna height for the base (1.735) and rover (2.0865).
