Abstract
A method is provided for discriminating and routing data packets in a satellite-based communication system ( ), comprising the steps of: (a) receiving an input data stream from an application residing on a transmitting device ( ); (b) selecting either a first spread spectrum code or a second spread spectrum code based on the quality of service (QOS) requirements associated with the first application; (c) applying the selected spread spectrum code to the input data stream, thereby generating a spread spectrum data stream; (d) transmitting the spread spectrum data stream from the transmitting device ( ) to a network routing device ( ); (e) correlating the spread spectrum data stream with the corresponding selected spread spectrum code to recover the original input data stream; and (f) routing the input data stream to either a low earth orbiting satellite ( ) when the first spread spectrum code is used to recover the input data signal or to a geosynchronous orbiting satellite ( ) when the second spread spectrum code is used to recover the input data signal.
