Filed:

May 22, 2001

Appl. No.:

09/862632

Inventors:

Ronald Y. Chan - Torrance CA
Daniel R. Lane - Santa Monica CA

Assignee:

TRW Inc. - Redondo Beach CA

International Classification:

H01Q 2100

US Classification:

343879, 343765, 343770, 244158 R

Abstract:

An antenna system for a satellite including a gimbal device, such as a bi-axial gimbal, that employs a first uni-axial gimbal providing movement in one direction and a second uni-axial gimbal providing movement in a perpendicular direction. The first gimbal is mounted to a platform bracket, which is part of a moveable platform. The first gimbal is also mounted to the second gimbal, and the second gimbal is mounted to a satellite bracket secured to the satellite. Both a receive antenna array and a transmit antenna array are mounted to the moveable platform. Therefore, movement of the first gimbal causes the combination of the receive and transmit antenna arrays to move in one direction, and movement of the second gimbal causes the combination of the receive and transmit antenna arrays to move in the perpendicular direction.

Assignee:

Northrop Grumman Corporation - Redondo Beach CA

International Classification:

H04B 7185

US Classification:

455 121, 455427

Abstract:

A technique for providing secondary DC power to certain satellite payload components to reduce the number of secondary power converters on the satellite. A frequency generator ( ) is used as a source of secondary DC power instead of providing separate secondary DC power converters. A plurality of secondary DC power lines is tapped off of the frequency generator ( ) and applied to certain satellite payload components, such as LNA/DCs ( ) and upconverters ( ). Additionally, the secondary DC power available from the frequency generator ( ) is used as a secondary DC power source for a satellite beacon assembly ( ) that provides a signal to a beacon antenna ( ).

International Classification:

H04B 7185

US Classification:

455318, 455259, 455 131

Abstract:

A frequency scalable, low self-generated noise frequency source generates coherent or mostly-coherent local oscillator signals and includes a common reference, a coherent set of high frequency references and specific local oscillators which may be non-coherent for each specific output frequency. Delay lines may be included in the paths to ensure time delay alignment. The use of these elements with this modular design allows the generation of multiple coherent local oscillators via replication of the modular design elements.

International Classification:

H04B007/185

US Classification:

Abstract:

A multi-beam satellite comprises an input section receiving a plurality of first spot beams and an output section transmitting a plurality of second spot beams. A payload architecture is coupled between the input section and output section. It flexibly and selectively switches and filters the first plurality of spot beams received by the input section and provides signals to the output section to be transmitted as the second plurality of spot beams.

International Classification:

H04B007/185

US Classification:

455/012100

Abstract:

A redundancy network is provided that may include a first unit having first unit primary components and first unit redundant components, and a second unit (coupled to the first unit) having second unit primary components and second unit redundant components. A signal may pass through the first unit primary components and through the second unit primary components based on a first control signal and pass through the first unit redundant components and through the second unit redundant components based on a second control signal.

International Classification:

H04B007/185

US Classification:

455/012100, 455/427000

Abstract:

A satellite is provided that routes signals on 0 to n channels to any one of M downlink beams. The satellite may include n first-stage switches each corresponding to one of the 0 to n channels, M multiplexing devices each to combine n/2 channels into one output channel, M second-stage switches to receive outputs from said M multiplexing devices and M downlink antenna ports coupled to the M second-stage switches.

International Classification:

H04B007/185

US Classification:

455/013400, 455/012100, 455/427000

Abstract:

A communications satellite has multiple HPA redundancy pools. All downlink feed signals driven by HPAs in any one of the HPA redundancy pools are placed on a first number of antenna apertures which is less than the total number of available antenna apertures and, in the event that a HPA driving a downlink feed signal fails, only one of the other HPAs co-located in that same HPA redundancy pool may drive that downlink feed signal. Each one of the HPA redundancy pools provides downlink feed signals to the same number, but a different unique combination, of antenna apertures and is located so that the waveguide run length between it and the furthest antenna aperture in the unique combination of antenna apertures containing downlink feed signals provided by it is minimized.

H04Q007/20

US Classification:

455/428000, 455/429000, 455/013300

Abstract:

A multi-beam satellite has an input section to receive uplink spot beams in a first range of frequencies and an output section to transmit downlink spot beams in a second range of frequencies. An IF section is coupled between the first antenna and second antenna. It down-converts the uplink spot beams in the first range of frequencies to intermediate signals in an intermediate range of frequencies, flexibly and selectively switches and filters the intermediate signals in the intermediate range of frequencies, and up-converts the intermediate signals in the intermediate range of frequencies to the downlink spot beams in the second range of frequencies.
