The National Geodetic Survey (NGS) officially began public operation of the web-based On-line Positioning User Service (OPUS) in March 2001 as a means to provide GPS users easier ac-cess to the National Spatial Reference System (NSRS). Through OPUS, our goal is to provide the means to accurately, re-liably, and quickly obtain consistent geo-detic positions.
