A turn-key Concept for active cancellation of Global Positioning System L3 Signal [PDF]

, 2010
We present a concept, developed at the National Astronomy and Ionosphere Center (NAIC) at Arecibo, Puerto Rico, for active suppression of Global Positioning System (GPS) signals in the 305 m dish radio receiver path prior to backend processing.

Positioning with the Global Positioning System [PDF]

International Astronomical Union Colloquium, 1980
AbstractThis year (1980) the U. S. Department of Defense has scheduled to have in operation six satellites of the Global Positioning System (GPS), which will provide timing and three dimensional position recovery potential to North America during certain segments of a day.

Relativistic Positioning Systems

, 2006
The theory of relativistic {\em location systems} is sketched. An interesting class of these systems is that of relativistic {\em positioning systems,} which consists in sets of four clocks broadcasting their proper time.
