Separation Management in the U-space: a key enabler to boost U3 services take- off.

03 Feb 2021


BUBBLES is an Exploratory Research Project funded by SESAR Joint Undertaking aiming at defining a concept of operations (ConOps) to provide separation management in the U-space and identifying safety and performance requirements for the involved services and systems. It will develop algorithms to compute the collision probability between UAS using separation minima to keep it under acceptable levels. Moreover, the project will investigate how AI can contribute to dynamically managing these minima using different separation methods and agents (from centralised strategic deconfliction to distributed self-separation). BUBBLES will follow an operation centric, risk-based approach, assigning separation minima and methods depending on the UAS ConOps and the available U-space services performance. BUBBLES will also extend the concept of Performance Based CNS to the UAS operations to draft safety and performance requirements.


This online workshop intends to share the project preliminary results with the UAS community and to receive feed-back to align the next steps with the needs of its stakeholders.
