Power Optimized System For Electric Propulsion Stationkeeping Geosynchronous Spacecraft

View page
US Patent:
7922124, Apr 12, 2011
Filed:
Dec 7, 2006
Appl. No.:
11/608229
Inventors:
James D. Soldi - Redondo Beach CA, US
Andrew I. Mactavish - Hermosa Beach CA, US
Assignee:
The Boeing Company - Chicago IL
International Classification:
B64G 1/10
B64G 1/26
B64G 1/44
US Classification:
2441588, 244169, 2441727
Abstract:
Systems and methods are disclosed employing electric propulsion stationkeeping in a cyclical manner to better match the cyclical pattern of power generated by the solar array system. For a typical orbit design, e. g. a geostationary orbit, North-South stationkeeping can be intermittently suspended, tolerating some additional drift but yielding in a very significant reduction in the required solar power system. If necessary, stationkeeping can be supplemented with a chemical thrusters during off periods for the electric propulsion. Because of this, the overall electrical power margin for the solar array system design can be reduced without compromising the mission performance.

Modular Spacecraft Payload Support Structure

View page
US Patent:
60534540, Apr 25, 2000
Filed:
Sep 4, 1998
Appl. No.:
9/148581
Inventors:
John V. Smolik - Granada Hills CA
Spencer C. Ku - Rancho Palos Verdes CA
Andrew I. Mactavish - Hermosa Beach CA
Mark A. Spiwak - Redondo Beach CA
Assignee:
Hughes Electronics Corporation - El Segundo CA
International Classification:
B64G 110
US Classification:
244158R
Abstract:
A modular payload support for placement in an enclosure defined by the sidewalls of a launch vehicle includes a central hub, a plurality of trusses, and a plurality of modular outer panels. Each of the trusses includes an inner edge secured to the hub and extends radially outward from the hub. Each of the trusses further includes an outer edge, and a modular outer panel is secured to each of the truss outer edges. Each modular outer panel is adapted for attachment to the vehicle sidewall, with each modular outer panel being sized to span the available distance between the truss outer edge and the vehicle sidewall. Each of the trusses is constructed of a number of layers or plies, so that the trusses may be tailored to meet strength and stiffness requirements of a contemplated application.
