RTK_Salient_Characteristics_ASF.docx

The USGS Wetland and Aquatic Research Center in Lafayette, LA seeks to obtain an Integrated GNSS system for use in remote and heavy/dense canopy areas. The GNSS receiver system should come with a Tilt compensation to offset any non-vertical measurements that need to be taken. This system needs to be compatible with our existing GNSS Trimble systems.
