The future of commercial satellite telecommunications
Abstract
Reasons for using satellites for telecommunications are reviewed, and the growth in demand for telecommunications is discussed with attention to the spectrum-orbit slot problem. Services competing for spectrum occupancy are indicated, and space limitations for locating additional orbits as well as frequency-band limitations are examined. Digital communications and time division multiple access, a procedure which permits more efficient use of available frequency bands, are explained, the effects of rain on satellite communications are described, and the characteristics of future systems which would use higher frequencies, bigger satellites, and digital communications are considered.
