Objectives and Topics


The objective of the workshop is to identify potential synergies between High Altitude Pseudo Satellites (HAPS) and satellites in the domains of Earth Observation, Telecommunication and Navigation. Based on the technologies and applications presented, the European Space Agency will decide on potential demonstration projects. The workshop discussion and recommendations will support the European Space Agency in identifying needs, opportunities and criticalities for the preparation of an ESA programme for HAPS, as well as in providing substantial input for its definition. ESA is inviting all interested parties from industry (manufacturers, technology providers, operators, service providers), science, academia, regulatory bodies, policy makers, as well data users to participate to the workshop which will also provide a forum for networking and interaction with European experts.


Contributions to the following topics are invited:

  • Platforms: State-of-the-Art and future HAPS.

  • Synergies of HAPS with:

    • operational and scientific Earth Observation missions, applications and services,

    • telecommunication systems, applications and services,

    • PNT (positioning, navigation and timing) systems, applications and services,

    • integrated applications and services: Earth observation + navigation + telecommunications.

  • Payloads, including miniaturisation, modular architectures to accommodate multiple missions, customization and standardization efforts.

  • Ground segment solutions for HAPS, including command and control, communications, user segment and on-ground data processing.

  • Demonstration activities and prototyping campaigns.

  • Operations solutions for HAPS.

  • Regulatory topics: airspace regulation for HAPS with a focus on Europe, airworthiness, spectrum.
