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 Boeing Phantom Eye is a high altitude, long endurance (HALE) liquid hydrogen-powered [1] unmanned aerial vehicle developed by Boeing Phantom Works. [2] The aircraft was Boeing's proposal to meet the demand from the US military for unmanned drones designed to provide advanced intelligence and reconnaissance work, driven by the combat conditions in Afghanistan in particular.

Designated RB-57F, the design was almost an entirely new aircraft with a three-spar wing structure of 122 feet span, powerful new Pratt & Whitney TF33-P-11 main engines and two detachable underwing J60-P-9s for boost thrust at high altitude. The aircraft carried high-altitude cameras which were able to take oblique shots at 45 degrees up to 60 ...

The Boeing SolarEagle (Vulture II) was a proposed High-Altitude Long Endurance (HALE) unmanned aerial vehicle solar-electric spy plane developed by Boeing Phantom Works. [1] The proposed aircraft had a wingspan of 393.7 feet (120.0 meters), and was intended to remain airborne for up to five years at a time without needing to land. [2]
The A160 continued with developmental flight tests in 2010, but test flights had already demonstrated greater endurance, higher altitudes, more extensive autonomy, and greater payload. [compared to?] The program had ambitious goals of a 2,500-mile (4,000 km) range, 24-hour endurance, and 30,000 ft (9,100 m) altitude. Flights were largely ...
