Abstract: The paper examines likely needs which can be foreseen from civil users of navigation systems, be they aviation, marine, or land. Differences between users in the USA and in Europe are considered. The need for full international discussion is stressed as a prerequisite for trust in the system. It is also argued that the USA has as much to gain from such discussion as has the rest of the world. The paper concentrates on the Navstar Global Positioning System (GPS), which is seen as a considerable advance on earlier navigation systems. Nevertheless, the international community has several anxieties. Selective availability is likely to hurt US users as much as those in Europe and the integrity issue is an area where international discussion and cooperation is considered to be particularly valuable.
