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 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 ...
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]
Tier I: Low altitude, long endurance. Role filled by the Gnat 750. [8] Tier II: Medium altitude, long endurance (MALE). Role currently filled by the Predator and MQ-9 Reaper. Tier II+: High altitude, long endurance conventional UAV (or HALE UAV). Altitude: 60,000 to 65,000 feet (19,800 m), less than 300 knots (560 km/h) airspeed, 3,000-nautical ...
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 .
