When working with a single base station, it is important that the rover GNSS receiver adjust the base position by its phase center offset.

If working with a local base with a GNSS receiver not from GeoMax, the antenna phase center information is not available. In this case it is necessary to create the antenna. Instead GeoMax GNSS receiver are preloaded.
