Satellite TV System

Most satellite system designers, noting the benefits of integrating satellite systems with terrestrial systems, proposed system architecture which would combine satellite and terrestrial system networks to various extents. Dual mode satellite/cellular hand held telephones were conceived.

International organizations, developing standards and formalizing concepts for third generation terrestrial systems, began considering the role of satellite systems in future system architectures. It was well understood that cellular systems would remain concentrated in populated areas where they are economically viable, leaving gaps in vast, sparsely populated areas which could best be covered by satellite systems. Thus, future systems would incorporate interfaces and interworking arrangements to support interoperability between terrestrial and satellite systems.

In parallel, an unabated growth in satellite navigation technology for mobile and personal use continued throughout the 1990s. The cost of GPS receivers plummeted to levels affordable by the masses. A number of applications, developed, combining navigation and communication capabilities. More recently, several non geostationary MSS systems have included navigation as a valueadded service. Recent advance in Satellite TV system produces clear picture quality and sound.
