Abstract

A communication system for mobile platforms includes a receiver subsystem (RS) and a transmitter subsystem (TS). A satellite is in communication with the RS and the TS of the mobile platform. A ground station includes a transmitter subsystem (TS) and a receiver subsystem (RS). The TS of the ground station transmits a forward link to the satellite and receives a return link from the satellite. The forward and return links include Fixed Satellite Service (FSS) data and Mobile Platform Satellite Service (MPSS) data in the same frequency band. The frequency band is the Ku frequency band between 10.7 and 15.0 GHz.

 a mobile platform including a transmitter subsystem (TS);    a satellite in communication with said TS;    a ground station including a receiver subsystem (RS),    wherein said TS of said mobile platform transmits a return link to said satellite and said ground station that includes Fixed Satellite Service (FSS) data in a second frequency band and Mobile Platform Satellite Service (MPSS) data in said second frequency band.    
     
     
         10 . The communication system of  claim 9  further comprising: 
 a mobile platform network connected to said TS; and  
 user communication devices (UCD) connected to said mobile platform network.  
 
     
     
         11 . The communication system of  claim 9  wherein said second frequency band is the Ku frequency band between 10.7 and 15.0 GHz.  
     
     
         12 . The communication system of  claim 9  wherein said return link is between 14.0 and 14.5 GHz.  
     
     
         13 . The communication system of  claim 9  wherein said TS of said mobile platform employs bulk compression on said FSS and MPSS data.  
     
     
         14 . The communication system of  claim 9  wherein TS of said mobile platform employs bulk encryption and padding on said FSS and MPSS data.  
     
     
         15 . The communication system of  claim 9  wherein said TS of said mobile platform applies multiple access coding to said FSS and MPSS data on said return link.  
     
     
         16 . The communication system of  claim 15  wherein said multiple access coding is selected from CDMA, FDMA, and TDMA.  
     
     
         17 . A method of providing broadband communications for mobile platforms, comprising the steps of: 
 providing a mobile platform including a receiver subsystem (RS);    communicating with said satellite and said mobile platform using a ground station with a transmitter subsystem (TS); and    transmitting a forward link to said satellite and said mobile platform using said TS of said ground station, wherein said forward link includes Fixed Satellite Service (FSS) data in a first frequency band and Mobile Platform Satellite Service (MPSS) data in said first frequency band.
