  • Frequency and timing synchronization and error correction in a satellite network
    Patent number: 7471720
    Abstract: An outgoing transmission carrier frequency at, for example, a remote terminal, may be adjusted based on a feature rate of an incoming transmission. The adjustment may compensate for error in the outgoing transmission carrier frequency. The incoming transmission may be from a satellite or hub, for example. The outgoing transmission may be the signal that is transmitted by an antenna, or the outgoing transmission may be converted to be at another carrier frequency such as a higher carrier frequency for ultimate transmission by an antenna. Also, a remote terminal may be synchronized to a satellite network with or without knowledge of the remote terminals' geographical location and with or without time stamps.

  • Multi-spot satellite system for broadband communication
    Publication number: 20020032003
    Abstract: The present invention relates to the field of two-way satellite communications and in particular, to high capacity multi-purpose satellite communication systems optimized for two-way broadband communications. The two satellites are collocated and utilize a complementary channel arrangement which facilitates full dual pole coverage continuity when one of the satellites fails. Four channels of either inbound or outbound may be associated with each spot-beam area. Two channels may be provided by each of the two co-located satellites and may be configured to have a specific predetermined relationship with each other.
