what are the parameters of the EMLID RS + antenna to enter in delta N / E / U to configure RTKLIB? U = instrumental height
In the position tab
yes, but what are the parameters of N and E?
delta N / E / U in RTKPOST should be the difference (in meters) between the point being measured and the antenna inside Reach RS+.
Normally you would calculate it like this:
|65mm||distance between Reach RS+ antenna and bottom mount|
|21.5mm||brass adapter height|
|2m||pole height (or tribrach height, etc.)|
|2.0865m||U for RTKLIB (antenna height above the measured point)|
N / E / U = 0 / 0 / 2.0865
And to add to what @bide says, then N/E is usually only for offsetting phase-center on a L2 (etc.) antenna, if I have understood the documentation correctly.
Yes, or it could also be used in the odd case where you are offset from the point because of an obstacle or something like that.
Better be good at reading that compass
Oh that bush-craft !
Don’t forget to drop in little bit of soap to break the surface tension on the water though or you might get a false fix from that needle!
