The effects of the ionospheric auroral zone on the propagation of very low frequency VLF/LF and HF radio waves
Principal Investigator: Bickel, John
Licenced Year(s): 1992 1990 1989
Summary: The Researchers will continue to collect data using an antenna and a computer operated VLF (very low frequency) signal receiving and recording equipment....


Development of a Backup Communications System
Principal Investigator: Strickland, John I.
Licenced Year(s): 1991 1990
Summary: The Researcher will install digital radio repeaters at several sites, monitor the signal strength; measure the accuracy of data transmission over the link; and establish the feasibility of the prototype design....


Large Aperture Coherence Experiment
Principal Investigator: Morris, John B.
Licenced Year(s): 1990 1989
Summary: A radio signal will be transmitted from Yellowknife, to Los Banos, CA, U.S.A. at three selected periods throughout the year. The signal reflects from the ionosphere, and in doing so, experiences distortion. The severity of the distortion must be evaluated at different times of the day as well as different times of the year. This information will predict the utility of high frequency antennas up to...
