High Altitude Aeronautical Platform Stations
HIGH ALTITUDE AERONAUTICAL PLATFORMS HAAPS- seminar report | HIGH ALTITUDE AERONAUTICAL PLATFORMS HAAPS- seminar report.DOC (Size: 258 KB / Downloads: 305)
ABSTRACT
Today’s global communications infrastructures of landlines, cellular towers, and satellites are inadequately equipped to support the increasing worldwide demand for faster, better, and less expensive service. At a time when conventional ground and satellite systems are facing increasing obstacles and spiraling costs, a low cost solution is being advocated.
This seminar focuses on airborne platforms- airships, planes, helicopters or some hybrid solutions which could operate at stratospheric altitudes for significant periods of time, be low cost and be capable of carrying sizable multipurpose communications payloads. The airborne-internet aircraft will circle overhead at an altitude of 52,000 to 69,000 feet (15,849 to 21,031 meters). At this altitude, the aircraft will be undisturbed by inclement weather and flying well above commercial air traffic. This type of network called HALO Network.
INTRODUCTION
HIGH ALTITUDE AERONAUTICAL PLATFORMS (HAAPS)
High Altitude Aeronautical Platform Stations (HAAPS) is the name of a technology for providing wireless narrowband and broadband telecommunication services as well as broadcasting services with either airships or aircrafts. The HAAPS are operating at altitudes between 3 to 22 km. A HAAPS shall be able to cover a service area of up to 1 '000 km diameter, depending on the minimum elevation angle accepted from the user 's location. The platforms may be airplanes or airships (essentially balloons) and may be manned or un-manned with autonomous operation coupled with remote control from the ground. HAAPS mean a solar-powered and unmanned airplane or airship, capable of long endurance on-station –possibly several years.
A high altitude telecommunication system comprises an airborne platform – typically at high atmospheric or stratospheric altitudes –
