The proposals must address technological solutions for autonomous aerial drone navigation in non-permissive environments. These solutions must be evaluated through the testing environment set up in the framework of the technological challenge.

The proposals must cover at least the following tasks as part of mandatory activities:
Generating knowledge:

• Research on new approaches for robust autonomous navigation of unmanned aerial vehicles and systems in non permissive environments.

Participation to the evaluation campaigns organised in the framework of the technological challenge, including:

• contribution to the exchanges with the other stakeholders for elaborating the evaluation plans;
• participation of the unmanned aerial systems and software modules in experimental field and data-based test campaigns managed by the challenge organisers, whereby performance measurements are conducted to assess navigation capabilities;
• collection and sharing of sensor data;
• participation to debriefing workshops.

The proposals should substantiate synergies and complementarities with foreseen, ongoing or completed activities in the field of autonomous drone navigation.

Functional requirements
The proposed technologies should meet the following functional requirements:

• The unmanned aerial vehicles and systems should be able to accurately estimate their positions and to go to a designated target area with high reliability in non-permissive environments, where GNSS signals and communications may be degraded or lost.
• The performances for these abilities should be measured through the test campaigns conducted in the framework of the technological challenge, using protocols and metrics based on those described in the preliminary evaluation plan provided as part of the call documents. Details about how the proposed approaches and systems will address the tasks outlined in the preliminary evaluation plan should be described in the proposals. Any relevant system performances measured in the context of previous technological challenges should be mentioned in the proposals.
• Systems should be able to record the data acquired through their sensors to enable full replay of flights and reproduction of experiments in a software environment. The types of data that can be shared with other teams should be described in the proposals.
• The proposed approaches should be relevant for future integration and operational missions, especially in terms of SWaP-C. The user interfaces should help users and in particular pilots to understand and anticipate the system behaviours.
