The requirements of the current users of ship- or aeroplane-to-land communication systems are analysed and the facilities now available-radio beacons and a variety of hyperbolic systems-are listed. It is postulated that only by using satellites as navigation aids can the standard of radio communication be raised to an adequate level. The advantages of a global satellite system using three geostationary satellites for radiolinks or six satellites to ensure radiolocation for mobile vehicles between latitudes 70 north and 70 south are analysed and possible applications beyond communication with mobile vehicles are suggested such as weather routing, shipping control, anticollision measures, search and rescue. The basic technical characteristics of the satellite system are given and the prospects for its development are considered.
