RS+ Elevation measure

Please, share original CSV file downloaded from the Reach as there’s no info about collection start/end time, solution status, RMS, sample count and antenna height.

I think I knew wher is my mistake
During collecting the point in the survey mode it gives me 2m higher, but when I accepted and save it and downloaded from the Reach view it looks good.
Many thanks all of you:heart_eyes::heart

What the rms means ? and it appears that if it higher it gives a good result . The reading under hearth from my CSV file.

Rms?

Can some one explain the RMS values during a survey, I come from the electrical eng field where RMS is the “truer” valvue of the effevice wave form… not sure what it means here.

Seems sokkia point 176 and reach rs+ point 222 is a difference of 0.1860885m (7.326 inches) for example.

The sokkia receivers are multi-frequency correct? vs. Single L1 emlid, so the sokkia would be more accurate for vertical in this case?

Emlid, is the antenna height 2.0865m shown in csv file just for record, but the elevation shown is correct and what to use for the actual point height… as antenna height is already accounted for?

So point elevation isn’t off 2.0865m but 0.1860885m (7.326 inches) off for points 176 and 222?

So point elevation isn’t off 2.0865m but 0.1860885m (7.326 inches) off for points 176 and 222?

And for points 182 and 226 is 0.0209 m. It looks good.
