本文介绍了南加州综合GPS网（SCIGN）的基本科学目标和观测目标。它还回顾了组织结构、项目管理和重要政策。本文还详细讨论了最近取得的成就，特别是1999年10月16日Hector Mine地震（Mw7.1）后的有效反应。详细讨论了建立连续GPS网络观测地壳时瞬态变形的科学动机，特别是它与1990年代东加利福尼亚剪切带断层相互作用和震后变形序列有关。截至2001年3月，共有239个SCIGN站在运行；其中170个最新的车站是由承包商安装的。第三阶段的网络建设最近以平均每周2个新站的速度完成。网络建设仍在继续，最后16个站点的建设将于2001年7月1日全部完成。
This paper describes the fundamental scientific and observational goals of the Southern California Integrated GPS Network (SCIGN). It also reviews the organizational structure, the project management, and important policies. Recent accomplishments are also discussed in some detail, in particular the effective response following the October 16, 1999 Hector Mine earthquake (Mw7.1). The scientific motivation for establishing a continuous GPS network to observe time transient crustal deformation is discussed in detail, especially as it pertains to the 1990’s sequence of fault interaction and postseismic deformation in the eastern California shear zone. As of March 2001, a total of 239 SCIGN stations are operating; 170 of the newest stations were installed by a contractor. The third phase of network construction was recently completed at an average rate of 2 new stations per week. Network implementation is continuing, and construction of the final 16 stations will be fully completed by July 1, 2001.
