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 ...

First stage engine failure caused explosion at T+77 seconds. 38 kg (84 lb) August 24 US: Explorer 5: Juno I: Failure
The Facebook Aquila is an experimental solar-powered drone developed by Facebook for use as an atmospheric satellite, intended to act as relay stations for providing internet access to remote areas. The Aquila first flew on 28 June 2016 with a second aircraft successfully flying in 2017.
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.
Ground track example from Heavens-Above.An observer in Sicily can see the International Space Station when it enters the circle at 9:26 p.m. The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes.
