| 摘要： | A readjustment of all Global Positioning System (GPS) survey control in the United States was completed in 2007 by the National Geodetic Survey (NGS). The adjustment was undertaken to resolve inconsistencies between the existing statewide High Accuracy Reference Network (HARN) and/or Federal Base Network (FBN) adjustments and the nationwide Continuously Operating Reference Station (CORS) system, as well as between states, and to develop individual local and network accuracy estimates. For these reasons, on September 24, 2003, NGS Executive Steering Committee approved a plan for the readjustment of horizontal positions and ellipsoid heights for GPS stations only in the contiguous United States. Classical surveys were not included in this readjustment. |
