LETTER FROM EDITOR Dear Readers, The European satellite communications community has actually played a prominent role in introducing small satellites and developing the technology. The largest number of programmes have been carried out by University of Surrey and Surrey Satellite Technology Ltd. These efforts have been complemented by participation of Matra-Marconi and CNES, by parallel developments in Italy and widespread studies. Small satellite communications requires system design and identification of markets; clever technology, particularly in microminiaturization of electronics; and mustering the necessary financial resources to proceed. In the case of experimental systems, the European efforts have been highly successful. The Russian systems will be successful technically, but may have financial problems in reaching a full capability. Small communications satellites tend to be associated with LEOs and hence represent a revolution in all respects. The European community appears to have a slight bias towards evolution, suggesting the use of mid-altitude inclined orbits for serving European geographic areas, rather than moving directly to inherently global low altitude orbits. The intermediate step also favors mid-sized satellites that may be more matched to today's industry for development and manufacturing. Since developments in microminiaturization of electronics and other key technologies are enjoying steady progress in Europe and Japan, a technology base is available to support any future movement towards smaller satellites.
