Would base configuration work with ardusimple wifi ntrip master, or are there some settings to change, as it doesn’t use usb? Been a few months since I last used U centre!
I have build up my base now and I used the config from here. But I wasn´t happy. My rover only showed 6-9 sats and fix was very unstable. I changed the rtcm messages from MSM4 to MSM7 and I get 13-15 sats.
Andreas, you mean the antenna for the rover or base?
At the moment I am testing in office: the base is a F9p at RPi and for the rover I use a m8t with rtknavi. So the rover is only L1. But I tried the Sapos-RTK as well and that gave me 13-17 sats and a stable fix. The fix of my own base is not so stable. Maybe the big, old oak 30 meters away is a problem. Until now I am not so happy with the reliability of the rtk fix. But MSM7 improved the signal a lot.
How can I find out if the antenna or its cable is sligthly broken?
Strangly I get a fix after a while, but then I loose it 10 minutes later and it doesn´t come back.
At the moment both base and rover antennas are very close to each other and rover doesn´t move.
“At the moment I am testing in office”
Office tests with RTK are usually not successful. GNSS antennas must have an unobstructed view of the sky in all directions.
The antennas are on the roof of my house. So this should be no problem. The trees around are a bit annoying, but I have no better place.
Is there any reason why I should use msm4 instead of msm7?
