摘要： Various aspects of the disclosure provide hybrid spacecraft capable of hosting both a remote sensing payload and a communications payload. A hybrid spacecraft includes an isolation system for a remote sensing payload that isolates the remote sensing payload from spacecraft dynamics and disturbances, and prevents interaction between the remote sensing and communications payloads. The hybrid spacecraft may also include provisions for a communications payload including metering structure for large aperture antennas, and scalable resources for accommodating a range of remote and communications payloads.

摘要： A system for providing attitude control with respect to a spacecraft is provided. The system includes a reaction wheel control module configured to control a number of reaction wheel assemblies associated with the spacecraft in order to control attitude, and a maneuver control module configured to use a number of gimbaled Hall Current thrusters (HCTs) to control the total momentum associated with the spacecraft during an orbit transfer. The total momentum includes the momentum associated with the reaction wheel assemblies and the angular momentum of the spacecraft. Using the gimbaled HCTs to control the momentum associated with the reaction wheel assemblies during the orbit transfer results in minimal HCT gimbal stepping.

摘要： A GPS-at-GEO system is provided that includes a receive antenna design that enables improved tracking of GPS space vehicle side-lobe signals. The receive antenna design is a conical mode helix antenna configured to produce a conical mode radiation pattern, which has zero gain at Nadir and higher gain in the side-lobe signal regions. The conical mode radiation pattern provides several advantages for GPS-at-GEO navigation applications. For example, this mode provides higher gain in the GPS space vehicle side-lobe signal regions for improved acquisition and tracking performance and lower gain at Nadir, providing reduced noise temperature and higher signal to noise ratio.
