TOOLIK GPS BASE

Toolik Field Station maintains a continuous GPS base station for use by the Toolik community and the general public. The base station runs continuously through the summer field season (May - August), with files permanently archived and available for download through this website (links below).

HISTORY

From May 2001 - August 2003 the base receiver was a Trimble ProXR (mapping grade), supporting code (RTK and post-processed) and carrier phase (post-processed) corrections. Under optimal circumstances, code corrected data can deliver accuracy to within several meters, and carrier corrected data can deliver sub-meter accuracy.

In May 2004 the Toolik Field Station GPS Base was upgraded to a Trimble 5700 (survey grade), which supports survey and mapping grade corrections (RTK and post-processed).

Please see the EquipmentPage for detailed descriptions of the base station components as well as GPS rover units available for use at the station.
