We have a Trimble R2 GPS receiver and we use Field Maps to collect sub-inch points with in the field. This has worked like a champ for years, but just recently we are having accuracy issues when in Field Maps. Before we could take points with about 1 inch of accuracy, where as now when we are in Field Maps, it can't get below 1 foot. If we open Trimble Mobile Manager it can get to that sub-inch accuracy, but as soon as we switch to Field Maps it jumps to 1-4 foot accuracy. I've noticed that when I connect to Trimble Mobile Manager after trying in Field Maps, it's only showing connections to the GPS and SBAS constellations, but eventually in TMM it will find the other constellations and get to sub-inch accuracy. Has anyone else come across this issue?
