Abstract

In 1997, Louisiana State University began construction of GULFNET, a geodetic system consisting of continually operating reference stations and episodic campaign targets. Originally built to support high precision measurement of subsidence and lateral normal fault related strain, the system was also designed to support geodetic-quality positioning. This system currently consists of four continuously operating stations and 24 episodic campaign targets and is supported by contracts with the National Science Foundation (NSF-EAR 9725330) and the Louisiana Board of Regents. The continuously operating stations will soon become certified by the National Geodetic Survey (NGS) as official parts of the Continuously Operating Reference System or CORS, that supports the National Spatial Reference System (NSRS). Funds originating from US Army Corps of Engineers (New Orleans District) through this proposed contract will permit the expansion of GULFNET by adding three additional continuously operating sites and the infrastructure to continue operation of the network. This new part of the system will come on line in early 2002 and will provide near complete coverage of the Louisiana coast.
