Global Positioning System Measurements Over a Strain Monitoring Network in the Eastern Two-Thirds of the United States

摘要

In November and December of 1987, the National Geodetic Survey (NGS) undertook the establishment of a 45-station Global Positioning System (GPS) network covering the United States approximately east of 105 west longitude. The network was established in support of the Nuclear Regulatory Commission (NRC) for the purpose of monitoring crustal strain in the area. GPS technology was used to perform measurements over the network. In addition to monitoring large-scale strain, the network will provide a basic framework to support more detailed GPS networks (established for geodynamic and surveying applications) which can monitor strain and deformation in the central and eastern United States.
