WorldFamousBrapples Posted August 10, 2012 Share Posted August 10, 2012 Hi all, I am working with a Trimble GeoXT 2008 model. It's set up in NAD 83, State plane feet (North Carolina). When in the field, and often connected to 6+ satellites, the top right of the screen indicates horizontal errors of 20+ feet! What can be going on here? Can this be related to "real-time settings" where I can choose to always use (or wait for) integrated SBAS, or I can choose to use uncorrected GPS in the event that a corrected signal is not available? The bit of experimenting I've done indicates to me that the unit rarely acquires a SBAS signal and makes data collection very inefficient. I can't find any settings that strike me as off, it all seems legit, except for this high horizontal field error. My post processed (i.e. differentially corrected) data indicates reasonable accuracy, always within <5 feet based on aerial images and the calculated horizontal error that Pathfinder Office gives me. Any ideas? Thanks. Quote Link to comment
