Aeronautical Satellites

A recent conference on Satellite Systems for Mobile Communications and Navigation held at the Institution of Electrical Engineers dealt with all manner of requirements for land, sea and air users. The papers mentioned here refer specifically to aeronautical users and the technology that will permit their large‐scale introduction in the 1990's. Capacity on satellites made available by Inmarsat (the International Maritime Satellite organization) means that voice and data services now undergoing proving trials together with the developments foreseen, will provide global communication in the near future.
