GPS Information & Receiver Performance Reports

GPS Receiver Testing Reports

Reports of GPS Receiver Accuracy tests made under tree canopy at 2 sites. Tests were made under eastern hardwood forests at the Ridley Creek, Pennsylvania test network and under western conifer forests at the Clackamas River, Oregon test network. The Trimble GeoXT, Trimble Pocket GPS, and the Garmin GPSMAP 76 GPS receivers were tested using National Standard for Spatial Data Accuracy testing procedures.

Report from the USFS GPS Steering Committee Meeting held in Phoenix, AZ, April 20, 2005


DRAFT Forest Service GPS Data Accuracy Standard Paper

The GPS Data Accuracy Standard provides direction on matching GPS equipment and field procedures to the various GIS accuracy requirements of the agency. The Standard is intended to provide agency direction for testing and reporting GPS accuracy in a consistent and statistically meaningful way. It is based on a review of past agency and federal accuracy standards with the intent of providing direction that is consistent with current federal standards.

Missoula Technology Development Center (MTDC) GPS Receiver Comparison

Dick Karsky of the MTDC has released a draft of the paper "Comparison of GPS Receivers Under Forest Canopy with Selective Availability Off". This paper compares the accuracy performance of various mapping and recreational grade GPS receivers under forest canopy.


Pacific Northwest Region and MTDC Receiver Reports

Drafts of four reports on GPS receiver performance and accuracy under Western Oregon tree canopy by Santiago Mancebo and Ken Chamberlain are now available. These reports cover the Trimble ProXR and GeoExplorer 3, four models of recreational type GPS receivers manufactured by Garmin and Magellan, and the Rockwell PLGR P(y) code receiver. The receiver tests were made at the Clackamas Test Network in Western Oregon.
