GPS systems to be demonstrated



Most of us think of the settings of scientific meetings in terms of darkened rooms with slide projectors, or arrays of bulletin boards and video screens with poster papers. One of the most visible sessions at the 1986 AGU Fall Meeting/ASLO Winter Meeting, however, will be a demonstration of the Global Positioning System (GPS) on the lawn and sidewalk area just across from the Civic Auditorium in San Francisco, Calif.

Although the demonstration will begin in the wee hours of the morning on Tuesday, December 9 (rain date: Wednesday, December 10), the instruments—at least three different pairs of GPS instruments from different manufacturers—will remain set up for examination during the morning sessions that day. The observations will be reduced with microcomputer software packages in an informal session on Wednesday afternoon, and the results of the measurements and reductions will be presented as part of a poster session on the morning of Thursday, December 11.
