Abstract

A system for bi-directional data content transfer between a plurality of mobile platforms, such as aircraft or cruise ships, and a ground-based control segment. The system includes the ground-based control segment, a space segment and a mobile system disposed on each mobile platform. The ground-based control segment includes an antenna which is used to transmit encoded RF signals representative of data content to the space segment. The space segment includes a plurality of satellite transponders, with one of the transponders being designated by the ground-based control segment to transmit the encoded RF signals to the mobile system. The mobile system includes steerable receive and transmit antennas. The receive antenna receives the encoded RF signals from the satellite transponder, which are thereafter decoded, demodulated, D / A converted by a communications subsystem and transmitted to a server. The server filters off that data content not requested by any occupants on the mobile system.

Description

technical field

[0001] The present invention relates to a global system for providing live television programming and two-way data services to mobile platforms, such as aircraft, using satellite communications. Background technique

[0002] Broadband data and video services, on which our society and economy increasingly depend, have so far not been readily available to users on mobile platforms such as airplanes, ships, trains and automobiles. While technology exists to deliver such services to all forms of mobile platforms, previous solutions have generally been expensive, have low data rates and / or are only applicable to a very limited government / military user market or certain High-end maritime market (such as cruise ships).

[0003] At present, users on the ground can obtain various broadcast and television services via satellite links. Such services include commercial DBS (Direct Broadcast Satellite, direct broadcast satellite) services (such as DirecTV 7 and EchoStar...
