According to base station setup documentation (https://emlid.com/setting_up_the_base/), with NTRIP correction signal from another public GNSS station, base station can self-compute its positon and achieve centimeter accuracy or sub-meter accuracy depending on how far away from the public GNSS station.
A few questions:
Is there a guideline on the distance limit between my base station and the public station to set up base station with centimeter accuracy?
Since the base station need NTRIP correction to determine its own coordinate, how to set up base station with centimeter accuracy when there’s no public GNSS station nearby?
How to tell NTRIP correction from another base station also has centimeter accuracy? If the other base station only has meter-level accuracy , then does it mean my base station will also have meter-level accuracy rather than centimeter accuracy?
For more details, I’m using Reach RS2 as receiver and Reach M2 as base station.
