ICARUS – H2020 – SESAR – 2019/2 – Ref. 894593

ICARUS project proposes a GNSS based altimetry solution to the challenge of the Common Altitude Reference system for drones at very low level airspace, through the identification of the navigation requirements applicable to Unmanned Aircraft Systems (UASs) and the definition of a new U-space service for UAS / Manned aircrafts altitude translation.

  • Common Altitude Reference for UAS
    Define technical requirements for high accuracy GNSS-based altitude measurement for drones, to enable a reliable and accurate common vertical datum.
  • Ground Obstacle Awareness
    Investigate the vertical accuracy and resolutions achievable by the actual Digital Terrain Model (DTM/DSM) services for ground obstacles clearance.
  • Barometric to geodetic translation
    Design a tailored U-space service for height transformation: geodetic measurement to a barometric reference system and vice-versa for UAS and Manned aircrafts.

ICARUS concept will be validated in a real operational environment, providing feedbacks and refinements to the initial definition. A final Concept of Operations (CONOPS) will be generated in the second part of the project.

our role

Topview is responsible and coordinator of the validation activities of the ICARUS prototype.
The concept will be tested through a validation campaign in the real operating environment: two UASs will fly into the same airspace, using the service in prototype version.
In particular, topview will take care of the definition of the operational scenario and its implementation, including a simulated general aviation aircraft and the analysis of the results.
