About the Basestation:

This basestation was set up to serve the needs of the faculty, staff, and students at Oklahoma State University.  We welcome outside GPS users to utilize this resource, but please keep in mind that support may not always be immediately available.

The Department of Geography at Oklahoma State University maintains a 12-channel Trimble Pathfinder Community Basestation that can be accessed via FTP.  The basestation receiver and data logging computer are located on the top of the Wentz Hall dormitory on the OSU main campus in Stillwater, OK.  Basestation files are maintained for 90 days and then removed from the system.
