Problems solved by technology

However, such aircraft may consume significant resources (i.e., power) in maintaining the robust position necessary to use such narrow beam antennas
this power is expended both in robust operation and in rapid compensation for transient changes in local flight conditions

Embodiment Construction

[0027] The foregoing summary, and the invention defined by the enumerated claims, may be better understood by referring to the following detailed description, which should be read in conjunction with the accompanying drawings. As stated below, the detailed description of a particular preferred embodiment of this communication system is not intended to limit the enumerated claims, but rather serves to provide specific examples thereof to allow building and using an embodiment of the present invention.

[0028] Referring to FIG. 1 , a communication system embodying the present invention includes one or more ground stations 102 , one or more aircraft 104 , and preferably one or more satellites 106 . The ground station is located in a cell 108 which is aimed by the aircraft's directional antenna. Each aircraft is positioned within a limited flight field at stratospheric altitudes, eg, between altitudes of 50,000 feet and 70,000 feet. Preferably, each flight location is arranged a...

Abstract

This disclosure provides a communication system using a high-altitude aircraft traveling at relatively slow speeds, which can remain airborne for long periods of time. The communication system uses the airplane as a long term high altitude platform that relays signals between one or more ground-stations and / or satellites, aircraft, and the like. The ground-stations have narrow-beam antennas that are aimable, permitting the aircraft to maintain a larger station than would otherwise be possible using the narrow-beam antennas. The ground-stations adjust their aim based on information either gained by tracking the aircraft's signal, or transmitted by the aircraft to the ground-station.

Description

[0001] This application claims priority to US Provisional Patent Application Serial No. 60 / 197,799, filed April 14, 2000, which is hereby incorporated by reference for all purposes. technical field [0002] The present invention relates to wireless communication systems, and more particularly to a wireless communication system using an aircraft having one or more ground stations. Background technique [0003] The long-standing need for high-bandwidth, short-distance connections to voice and data stream end users has rapidly increased. This need for increased communication capabilities exists both in urban areas with solid communication infrastructure and in less developed areas that lack such infrastructure. Communication signals may be communicated to end users via many different types of communication systems. Wired, terrestrial systems generally provide high speed communications for very large bandwidth signals. However, the infrastructure for the above system is expens...
