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 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 .
In spring 2019, Aurora plans to fly a High-Altitude Long Endurance drone powered by solar cells and batteries, Odysseus. Aurora won a DARPA CRANE (Control of Revolutionary Aircraft with Novel Effectors) grant to test a small-scale plane that uses compressed air bursts instead of external moving parts such as flaps.
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 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 ...
Design, build, and demonstrate the Global Observer UAS for a 5 - 7 day endurance for 55,000 to 65,000 feet (17,000 to 20,000 m) altitude missions with 380-pound, 2.8 kW payload capacity. The system had to be capable of being transported by a C-130 aircraft.
