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.

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 BAE Systems Persistent High Altitude Solar Aircraft (PHASA-35) is a High-Altitude Long Endurance (HALE) unmanned aerial vehicle (UAV) developed by BAE Systems in collaboration with Prismatic. Designed as a cheaper alternative to satellites, the aircraft can be used for surveillance , border control , communications and disaster relief with ...
The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. It is boosted into space by a launch vehicle , then re-enters Earth's atmosphere and lands as a spaceplane .
The Scaled Composites Model 281 Proteus is a tandem-wing high-altitude long-endurance aircraft designed by Burt Rutan to investigate the use of aircraft as high-altitude telecommunications relays. The Proteus is a multi-mission vehicle able to carry various payloads on a ventral pylon. The Proteus has an extremely efficient design and can orbit ...
The Boeing Condor is a high-tech test-bed piston-engined aerial reconnaissance unmanned aerial vehicle with a wingspan of over 200 feet (61 m). [ 1 ] Carbon-fibre composite materials make up the bulk of the Condor's fuselage and wings.
