The Iceland GPS Geodetic Field Campain 1986



For a number of years, geophysicists have followed the development o f the Navigation Satellite Timing and Ranging (NAVSTAR) Global Positioning System (GPS) in anticipation of conducting geodetic surveys of such a size and accuracy [Bossler, 1984] that the detailed monitoring of neotectonic movements on a regional scale will be permitted. During 1986 the technology had considerable application in this field, including studies conducted in California, Mexico, the Caribbean, and New England. The largest of the 1986 projects was a survey of Iceland that involved ultimately the use of 26 TI4100 receivers by over 30 scientists from nine nations. Twenty different universities, institutions, and companies were involved in the effort. This article briefly describes the field campaign and the concurrent data processing
