US Patent:

7040210, May 9, 2006

Filed:

Feb 18, 2003

Appl. No.:

10/369370

Inventors:

Gregory M. Richards - Colleyville TX, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

F41B 10/14

US Classification:

89 114, 244 329

Abstract:

An apparatus includes a restraint for restraining a first control surface in a stowed configuration and a severing mechanism for parting the restraint to allow the first control surface to move into an operational configuration. A vehicle includes a body, a first control surface rotatably mounted to the body, and a restraint attached to the first control surface for restraining the first control surface in a stowed configuration. The vehicle further includes a severing mechanism for parting the restraint to allow the first control surface to move into an operational configuration. A method includes attaching a restraint to the control surface to restrain the control surface in a stowed configuration and cutting the restraint to allow the control surface to move to an operational configuration.

Abstract:

An apparatus having processing circuitry configured to estimate beyond line-of-sight emitter location may be configured to receive signal information indicative of TDOA and FDOA measurements at a first receiver and a second receiver. The signal information may be generated based on indirect wave signals received from the emitter at each of the first and second receivers. The processing circuitry may be further configured to employ a first analytical model of the ionosphere to generate coarse TDOA and FDOA contour maps, and generate a first geolocation estimate based on the coarse TDOA and FDOA contour maps.
