Accuracy of Time Transfer in Satellite Systems
National Academies, 1986 - Artificial satellites in navigation - 85 pages
Report evaluates and determines adequacy of corrections for relativistic effects in present Air Force programs to perform their mission, e.g., the global positioning system (GPS). Report determines adequacy of present methods for meeting Air Force mission needs and explains future uses and needs for time transfer, including use of time transfer to test the postulates of relativity theory. Keywords include: global positioning system, NAVSTAR, relativistic effects, and time transfer.
