for people willing to do some ntrip testing, I made my station available as a NTRIP source on rtk2go.com
the stream feed from the trimble station is mountpoint MAGC
the stream feed from the F9P ardusimple is mountpoint MAGC_UBX
Both streams send MSM7 messages (GPS+GLO+GAL+BDS) at 1Hz
both share the same antenna as described here http://rgp.ign.fr/STATIONS/#MAGC
I cheated and the coordinate published in the MAGC_UBX 1005 message is actually the L1PC coordinates.
I will probably not let it on a permanent fashion, but would be interested to see “long range” tests if people want to try !
