US Patent:

56685653, Sep 16, 1997

Filed:

Dec 22, 1994

Appl. No.:

8/362047

Inventors:

Anthony D. Robinson - Leesburg VA

Assignee:

Orbital Science Corporation - Dulles VA

International Classification:

H01Q 136
H01Q 1520

US Classification:

343895

Abstract:

A flexible feed line is provided for use with a selectively deployable antenna system. The feed line is resilient and expandable so that it can maintain connections within antenna feed circuits while the antenna is being deformed or moved for stowage. An antenna system for use with the feed lines of the present invention may consist of a deployable quadrifilar helical antenna elements having four resilient conductive strips bonded thereto. Flexible feed lines are attached to each of the conductive helical strips. The feed lines expand to accommodate the shape of the antenna elements when compressed for stowing and return to their operating shape when deployed, thus providing identical feed paths to each of the antenna conductors when the antenna system is deployed.

Appl. No.:

8/896728

Inventors:

Anthony D. Robinson - Leesburg VA

Assignee:

Orbital Sciences Corporation - Dulles VA

International Classification:

H01Q 136

US Classification:

343895

Abstract:

A helical antenna structure is deformable and capable of being stowed in a small volume. At deployment, the helical antenna structure uses the stored strain energy in its resilient helices to revert to its original shape without the use of any outside force. Multiple antenna structures can be linked using a plurality of resilient lenticular shaped hinges.

International Classification:

E05F 108
E05F 314
E05F 502

US Classification:

16 54

Abstract:

A shear viscous damped hinge uses a negator spring and a high viscosity fluid to provide a relatively slow and controlled deployment of the hinge. Shear damping of the fluid slows the angular velocity of the hinge. The invention reduces the end of travel impact loads thereby reducing the risk of damage to the hinge and the object rotated by the hinge. The hinge is particularly useful in, but not limited to, spacecraft applications.

International Classification:

H04B 7/185

Abstract:

A spaced-based system is provided to simultaneously track and monitor one or more ocean going vessels at any point on the earth. The system includes a plurality of space vehicles or satellites each satellite includes an AIS communications payload to receive AIS signals including AIS information transmitted from the one or more vessels and to transmit the received AIS information. The system also includes a plurality of ground earth elements. Each ground earth element includes a receiver to receive the AIS information transmitted from one or more of the plurality of satellites to globally track and monitor the one or more vessels based on the AIS information received from the communications payload. The plurality of satellites are distributed in two or more orbital planes located at a substantially common altitude and having a substantially common inclination. In particular, the satellites may be deployed in a low earth orbit constellation.
