| 20120119034 | Deorbiting a Spacecraft from a Highly Inclined Elliptical Orbit - Deorbiting of an earth-orbiting satellite is accomplished by executing an orbit transfer maneuver, the orbit transfer maneuver resulting in transference of the satellite from an operational orbit to a disposal orbit, where the disposal orbit is substantially circular and has a nominal radius of approximately, 31,000 kilometers. The operational orbit may be substantially geosynchronous and have at least one of (i) an inclination of greater than 10 degrees and (ii) a nominal eccentricity greater than 0.1. Alternatively, the operational orbit may be a medium earth orbit. | 05-17-2012 |
| 20120097797 | SPACECRAFT MOMENTUM MANAGEMENT - Three-axis spacecraft momentum management is performed for a spacecraft traveling along a trajectory, by an actuator including at least one thruster disposed on a single positioning mechanism. As the spacecraft travels along the trajectory, a desired line of thrust undergoes a substantial rotation in inertial space. When the spacecraft is located at a first location on the trajectory, the single positioning mechanism orients the thruster so as to produce a first torque to manage stored momentum in at least one of a first and a second of the three inertial spacecraft axes. When the spacecraft is located at a second location on the trajectory, the single positioning mechanism orients the thruster so as to produce a second torque to manage stored momentum in at least a third of the three inertial spacecraft axes. | 04-26-2012 |
| 20120094593 | Broadband Satellite with Dual Frequency Conversion and Bandwidth Aggregation - A broadband satellite having a payload subsystem configured to provide dual frequency conversion and bandwidth aggregation is communicatively coupled (i) to at least one gateway by a feeder link operating at a first frequency band; and (ii) to a plurality of user terminals by user links operating at a second frequency band. The payload subsystem has a first and a second frequency converter a satellite feeder link antenna feed, and a satellite user link antenna feed. The first frequency converter down converts, to a third frequency band, as an aggregated block, signals received at the satellite feeder link antenna feed from the gateway via the feeder link. The third frequency band is substantially lower than both the first and second frequency band. The down converted signals are routed to the second frequency converter for up converting to the second frequency band for transmission over the user link to the user terminals. | 04-19-2012 |
| 20120068019 | High Capacity Broadband Satellite - A high capacity broadband service is provided from an Earth orbiting satellite having a payload that includes multiple large antennas, the satellite having an inverted configuration when deployed on orbit. The satellite has an aft surface proximate to a launch vehicle structural interface, a forward surface opposite to said aft surface, and a structure disposed therebetween. In a launch configuration, two or more deployable antennas are disposed, undeployed, on or proximate to and forward of the forward surface; on-orbit, the payload is operable when the satellite is disposed with the aft surface substantially Earth facing while the forward surface is substantially facing in an anti-Earth direction. Each deployable antenna is disposed, so as to be Earth facing, when deployed, in a position substantially forward and outboard of the forward surface. | 03-22-2012 |
