Hi @LN and the team.
Just in time to test with success -) the 2021.3 beta and the "mock-location accuracy usage" new parameter.
@Remy_CLEMENT and I followed a course this week by Julien Ancelin about the open GNSS RTK Centipede network he initiate and this morning we can test the v2021.3 beta with success, using a DIY RTK Rover behind a Lefebure NTRIP Client
Here are the screenshots of the taken geopoint and pictures of the the rover.
One (out of topic) learn is that with such a DIY material, without using the RTK correction, we got better than 50cm accuracy And 1 cm with the RTK activated
