We are using a Trimble R10 as an external GPS for the Collector App by using the NMEA adapter from Aman Enterprises. We are also connected to our local NTRIP corrections service. When we got it all set up an running the horizontal accuracy peaks out at 3.8 ft. We need it to be more accurate than that, and we know the R10 is very capable of delivering the accuracy. Does anyone know a fix for this? We should be getting sub foot accuracy.
