What is ICARUS
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.
U-space is a set of new services relying on a high level of digitalisation and automation of functions and specific procedures designed to support safe, efficient and secure access to airspace for large numbers of drones. As such, U-space is an enabling framework designed to facilitate any kind of routine mission, in all classes of airspace and all types of environment – even the most congested – while addressing an appropriate interface with manned aviation and air traffic control.
The ICARUS project has strong links both with the previous SESAR Exploratory Research 2016 studies and with the actual ongoing SESAR projects such as DACUS and BUBBLES. Other initiatives as EC EGNSS studies and other international UTM initiatives will be considered during the lifetime of the project.
The Common Altitude Reference System (CARS) document developed by EuroControl and EASA represents the starting point for ICARUS investigation.
In this discussion paper EUROCONTROL and EASA have published some potential options for the resolution to the Common Altitude reference problem for drones. The conclusion of the study outlines three options covering different approaches to address the problem (GNSS/ barometric / Mixes approach). ICARUS represents the follow up of such analysis, with the enforcement of the CONOPS proposed in a relevant operational scenario.
ICARUS will consider the outcome of CORUS project in accordance with the classification of the airspace volumes provided in the final CONOPS (X, Y, Zu, Za).
In fact, the CONOPS proposed by CORUS and the related airspace architecture will represent a solid benchmark to start ICARUS study for the best possible elicitation of CONOPS and the proposed service.
At global level, ICAO has proposed a common UTM framework, in which recognizes the need for a common altitude reference system to ensure safe vertical separation between unmanned and manned traffic.
