Satellite communications study for the atmospheric environment service

Results of a recent evaluation of satellite communications technology for use by the Atmospheric Environment Service of Canada are discussed. In particular, attention is given to traffic forecasts, definition of network options, development of evaluation criteria, and analysis of network options. It is shown that larger satellite networks are much more cost effective than smaller ones, providing added stimulus for integration of traffic. The integration can take several forms, including the amalgamation of different types of traffic from one user and the sharing of a satellite network by a number of user organizations. It is also shown that an organization with a moderate traffic volume can use satellites cost-effectively, provided the optimum network and implementation strategy is defined and adopted.
