The accuracy is clearly diminished when going into shielded areas but that is inevitable. However, if I return to the same track 10 minutes later, it will record a track with the exact same shape (within ~0.3m) but it is typically displaced by 1m or worst case even 2m. That is, if I walk around a small boulder, I can easily resolve that, giving an estimated resolution of ~0.3m. I can confirm that the ZED-F9P board without RTK gives <1m resolution but ~1-2m accuracy. This allows SW maps to download a Google Maps background (not essential) and also to receive NTRIP messages for RTK (I can confirm this works, just haven't had increased accuracy yet). I use an iPhone (my regular phone) to set up a Personal Hotspot that my Android phone can connect to. The sketch app is still a bit buggy and doesn't always record your track properly (in particular not when the app is not running in front, e.g., when you lock your phone to do a bit of running). The OCAD Sketch app can then be used with location information through mock GPS from the GNSS board. A message shoudl appear that a mock location is now used.
