Appl. No.:

11/614950

Anthony D. Monk - Seattle WA, US
Janet King - Redmond WA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

H01Q 3/00

US Classification:

342359, 342354, 342364

Abstract:

A system and methods for aligning an elliptical beam of an antenna to a line-of-sight from the antenna to a remote receiver are disclosed. The methods offset the antenna from an initial pointing direction in an antenna pointing coordinate system. Coordinates of the pointing offsets are determined in the E-plane and H-plane of an antenna beam coordinate system. The method then converts the coordinates of the pointing offsets from the antenna beam coordinate system into coordinates of offset points each located in the antenna pointing coordinate system according to the polarization angle of the E-plane and the H-plane, and performs a tracking algorithm using relative signal strength measurement data at the initial pointing directions and at the coordinates of the offset points. The true location of the center/peak of the elliptical beam is calculated in azimuth/elevation planes of the antenna pointing coordinate system.

International Classification:

Abstract:

Implementations are described that use a control center to maintain a list of registered mobile platforms that are pre-authorized to make use of the satellite-based transponder to transmit and receive data content to and from the base transceiver. The control center may cause the base transceiver to transmit at least one polling message, the polling message carries information addressed to a specific aggregate group of the registered mobile platforms and includes a return channel which may be used by a mobile platform to communicate with the base transceiver. In one implementation, the control center protects the system from exceeding power spectral density (PSD) statistical limits by using the mobile platform in the group that has a greatest power spectral density signal as the PSD that the aggregate group will generate.
