A high altitude platform can provide observation or communication services. A high-altitude platform station (HAPS, which can also mean high-altitude pseudo-satellite or high-altitude platform systems), also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites.
The Hawk30 flying-wing is a development of the NASA Pathfinder and NASA Helios high-altitude, long-endurance unmanned aircraft built by AeroVironment for NASA. [2] Resembling the 1999 Helios, the tailless aircraft is a 256 ft (78 m) span flying wing with 10 electric-driven propellers. Orbiting at 65,000 ft (20,000 m), it is solar-powered by day ...
The development of the aircraft is ongoing and currently part of the Airbus High Altitude Pseudo-Satellite (HAPS) programme. [43] It is intended to provide both surveillance and connectivity solutions for months at a time. [44]
The Zephyr is a series of high-altitude platform station aircraft produced by Airbus. They were designed originally by QinetiQ, a commercial offshoot of the UK Ministry of Defence. In July 2010, the Zephyr 7 flew for 14 days. In March 2013, the project was sold to Airbus Defence and Space. In the summer of 2022, the Zephyr 8/S flew for 64 days.
World view also offer traditional, uncontrolled high-altitude balloon flights (which just drift freely, without any control of direction of travel, in the winds of the high atmosphere) with their so-called Z-Class flight vehicle. The Z-Class vehicle has much larger payload capability and higher operating altitude compared to the Stratollite.
Aquila is intended to fly at altitudes of up to 90,000 feet (27,000 m) during the day, [1] dropping to 60,000 feet (18,000 m) at night, with an endurance of up to three months, providing Internet service to a 50 miles (80 km)-radius area below its flight path; [3] if communications spectrum was assigned for the project, it would allow the 66% ...
