After doing the last firmware update on the two (2) S100s, it became very difficult, if not impossible, to get a fixed solution (fixed rtk),
in clear sky conditions, 12 or more satellites (GPS+GLONASS and portuguese national CORS ReNEP), good net connection and base at short distances (< 20km). This happened at 2km, 5km, 10km.
This problem is occurring in the same location where before the firmware update I got a fixed solution easily, in the two s100.
What could be the problem?
