A NEAR-network isn’t an independent network.
Rtk2go puts all stand-alone-stations in a (smaller) radius together and creats the near-network.
If you insert NEAR-Swiss as Mountpoint at your rover AND sends the GGA-message rtk2go automatically chooses the nearest station and sends this correction-data to you.
But using this near-networks you have to be carefully! If the different mountpoints aren’t all at ETRS89 and you are switched to an other mountpoint there maybe other results!
