The use of commercial Low Earth Orbit satellite systems to support DoD communications
(Monterey, California. Naval Postgraduate School, 1996-12)
Within the next five years there will be a proliferation of commercial Low Earth Orbit (LEO) satellite systems providing voice/data services to anywhere in the world. Instead of investing heavily in new satellite systems, ...
Comparative analysis of selected radiation effects in Medium Earth Orbits
(Monterey, California. Naval Postgraduate School, 1997-12)
Satellite design is well developed for the common Low Earth Orbit (LEO) and Geosynchronous Orbit (GEO) and Highly Elliptical Orbits (HEO), i.e., Molniya, cases; Medium Earth Orbit (MEO) satellite design is a relatively new ...
The applications in military communications of Low and Medium Earth Orbit Commercial Satellite systems
(Monterey, California. Naval Postgraduate School, 1997-09)
At the dawn of the 21st century several Low and Medium Earth Orbit Commercial Satellite constellations will be operational and they will be able to provide high bandwidth Global Communications in voice, data and multimedia ...
Analysis of digital cellular standards
(Monterey, California. Naval Postgraduate School, 1996-06)
Cellular communications has become one of the fastest growing segments in the telecommunications industry. The demand for cellular services has risen beyond all expectations. With the current growth of the analog cellular ...
GPS signal phase tracking using a Kalman filter
(Monterey, California. Naval Postgraduate School, 1997-06)
One of the more significant error sources in using the Global Positioning System for attitude determination of aircraft and earth orbiting satellites is multipath interference. The GPS signal is reflected from the spacecraft ...
Monitoring information systems to enforce computer security policies
(Monterey, California. Naval Postgraduate School, 1999-09-01)
Many computer security policies are written relatively vaguely. In many ways this is intentional to allow for easier access to all the functionality of the computer network. However, too much leeway allows users, without ...
Error probabilities of spread spectrum systems in [an] ultra wideband source (UWBS) interference
(Monterey, California. Naval Postgraduate School, 1996-09)
This thesis investigates the potential jamming capabilities of an ultra wideband source (UWBS) jammer on the direct sequence (DS) and frequency hopping (FH) spread spectrum systems using the Advanced Communication Link ...
Employment of indications and warning methods to forecast potentially hostile revolutions in military affairs
(Monterey, California. Naval Postgraduate School, 1995-09)
The basic premise of a Revolution in Military Affairs is that changes in technology doctrine, and organization have the ability to render existing methods of warfare obsolete. Two distinct visions of a future RMA are ...
