Toolik Field Station GPS Survey System

A geodetic GPS survey system, consisting of dual-frequency base station and roving receivers capable of centimeter-level accuracy, is available at Toolik Field Station to meet the surveying needs of researchers working in the vicinity of Toolik Lake on the north side of Alaska's Brooks Range. Real-time kinematic (RTK) broadcasts provide real-time capability within a ~5km line-of-sight vicinity of Toolik, and centimeter-level accuracy can be realized over 100 kilometers away from the station by collecting and post-processing data.

This system consists of a Trimble NetR8 base receiver, a Trimble 5700 roving system, associated RTK radio equipment, and a base station computer for data management. Both survey grade and mapping/GIS grade equipment are supported. The bulk of the technical support, system maintenance, and interface with the science community is handled by the Toolik Field Station GIS staff. UNAVCO is available to provide backup support and specific training.
