  • Patent number: 6226493
    Abstract: A geosynchronous satellite system (10) uses crosslinks (30) between geosynchronous satellites (16) which travel along the same ground path (18) or are located within a common orbital slot (32) in order to increase traffic-carrying capacity and decrease signal delays. The geosynchronous satellites (16) can have substantial angles of inclination to provide high quality coverage within a wide range of latitudes (40, 42). In addition, the orbits can be elliptical, resulting in concentrated network capacity in either the northern or southern hemisphere. For co-positioned satellites (171-174), orbit perturbations are introduced in order to eliminate crosslink blockage caused by intervening satellites (172, 173). Methods for deploying and operating the geosynchronous satellite system enable network capacity to be modified (708) and routing (804), crosslinks (1008), and handoffs (908) to be controlled.

  • Patent number: 6104911
    Abstract: A method and apparatus for providing an economically viable satellite communication system (100) for voice, data, and video using satellite diversity to augment capacity of the system, to mitigate the effects of network operational issues such as the effects of satellite failure and/or satellite blockage, and to maintain service links (180) in a cost-effective manner. Satellite diversity is incorporated into the communication architecture, along with the ability to utilize all satellites (110) within a communication range (or view) of one or more service regions (197). Management methods are used to allocate satellite diversity to enhance service and mitigate network operational issues. Satellite constellation (120) is designed to maximize the availability of satellite diversity as a resource.

  • Patent number: 6088572
    Abstract: Multiple, different, independent constellations (10, 20) of satellites (2, 21-23) share a portion of a common frequency spectrum such as a single carrier frequency. The satellites' antennas (11) may be either multi-beam or omni-directional, while those of earth stations (13, 14) are directional. When interference occurs between communications of a satellite (31) of a first constellation (10) and a satellite (41) of a second constellation (20), any of several interference-mitigation options may be employed, such as the first satellite (31) handing off communications to a second satellite (32) of the same constellation (10), or temporarily suspending communications. The remedial action may occur in response to either predicted or detected interference.

  • Patent number: 6007027
    Abstract: A method (100) for providing continuous communication service from a partially populated satellite constellation includes deploying one or more phases of satellites to populate one or more sets of orbital planes (210), and providing continuous communication service from the one or more sets of orbital planes. Satellites (320) in each phase of satellites can be positioned to reside substantially the same as a position in which they will reside in a fully populated satellite constellation thereby eliminating the need to relocate satellites in the fully populated satellite constellation. Also, a communication unit (600) and a method (700) for the communication unit to communicate in a satellite communication system having a satellite constellation capable of being deployed in a plurality of phases is provided. The communication unit is capable of communicating with the satellite communication system at various minimum elevation angles during various phases of deployment.
