HIGH LATITUDE SOUND BROADCASTING FROM SATELLITES.

To date, it has been assumed that direct sound broadcasts would be made from satellites in equatorial orbits. However, it is proposed that it would be economically more attractive to use high-eccentricity, high-inclination orbits over the northern temperate zones for such services. Direct sound broadcasting will have to service simple, low-cost receivers and antennas that will only function with satellites near the zenith. With this in mind, the performance of 26 MHz broadcasts to extend current international broadcasts and 1500 MHz domestic FM stereo transmissions is examined. It is concluded that such satellites must be considered in any future examination of Canada's communications needs.
