Presenter: Matt Alexander, Vice President, Anatum Field Solutions, LLC, Beaverton, OR

We field-tested five Bluetooth-enabled GNSS submeter units to compare accuracy and precision for usage in a mobile GIS workflow.  We also included a Trimble handheld GNSS unit for accuracy comparison to the Bluetooth GNSS receivers. Units were tested against known benchmarks. Points were digitized with a tablet paired to each test GNSS unit. Accuracy and precision was determined by using ArcGIS to compare collected point data to known benchmarks. Tests found that in ideal, clear-sky conditions, all GNSS units performed to their specifications. However, when tested in difficult conditions with varying amounts of tree canopy overhead, performance differences became apparent.
