AIRBORNE CONSTELLATION OF COMMUNICATIONS PLATFORMS AND METHOD

摘要

an airborne constellation (10) is disclosed with a plurality of individual lighter-than-air platforms (12) spaced apart above a contiguous geographic area within a predetermined altitude range so that ubiquitous line of sight coverage of the geographic area is provided. Each of the plurality of platforms (12) includes an enclosure holding a regulated volume of low densi ty gas for buoyancy of the platforms. Each of the plurality of platforms furthe r includes a signal transmitting device attached to the enclosure by which signals from the platform may be transmitted to the contiguous geographic ar ea.
