High Altitude Pseudo Satellites (HAPS) operating for extended periods at an altitude of approximately 20 km complement and extend the capabilities of satellites in the domains of Earth observation, telecommunication and navigation. HAPS, in synergy with satellites, offer unique capabilities for the development of value adding applications and science.

With over 200 participants, the HAPS4ESA 2017 workshop was the first meeting in Europe bringing together HAPS system, payload and applications developers, institutional stakeholders, space agencies and scientists.

In 2019, building on this success, the European Space Agency again reached out to the Earth observation, telecommunication and navigation communities to review the state-of-the-art and the future perspectives of HAPS in a changing Space 4.0 environment and with a specific focus regarding potential ESA HAPS activities (decided at the ESA Council at Ministerial level in 2019, Space19+).
