Fixed RTK at all times. Without a doubt the S100 is a great receiver.
Sería bueno probarlo en lugares boscoso mucha vegetación,
Test under Vegetation.
Taking points at the edge of the garden, we already started to have fixed RTK loss in some cases (especially just below the treetops). However, by withdrawing from the area and returning, you can recover fixed RTK and maintain it.
I would say that this is the limit where it could be useful in RTK.
I have had difficulties in more open environments than this one with much more expensive receivers.
