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

1997年，路易斯安那州立大学开始建造GULFNET，这是一个由连续运行的基准站和间歇性活动目标组成的大地测量系统。该系统最初是为了支持沉降和横向正断层相关应变的高精度测量而建造的，同时也是为了支持大地质量定位而设计的。该系统目前由4个连续运行的台站和24个间歇性活动目标组成，并得到了与国家科学基金会（NSF-BS 9725330）和路易斯安那州董事会的合同的支持。连续运行的台站将很快被国家大地测量局（NGS）认证为支持国家空间参考系统（NSRS）的连续运行参考系统（CORS）的正式组成部分。来自美国陆军工程兵团（新奥尔良地区）的资金通过这项拟议的合同将允许通过增加三个额外的连续运行站点和基础设施来扩展GULFNET，以继续网络的运行。该系统的这一新的部分将于2002年初投入使用，并将几乎完全覆盖路易斯安那州海岸。
