DRAMA (AMMO CCN#2) - Drone Risk Assessment and Management in Airports

You are here

Objectives of the service

The availability and use of drones for commercial and private use, are growing substantially. Therefore drones are an increasing challenge for airports and the aviation industry in general, as they can cause a delay in Airline schedules if a drone is blocking departure corridors of an airport, or even damage an aircraft or worse in the case of a collision.

Therefore the process of keeping drones out of airport restricted zones are vital for flight safety. Airports are tasked, by governmental safety regulations and demands by airlines, with implementing drone detection and mitigation solutions to reduce the risk of collisions between drones and aircraft in airport surroundings. Over the last years, traffic has been disrupted at major airports like Heathrow, Gatwick, and Frankfurt because of illegal drone operations, generating critical operational issues and high associated costs.

With the DRAMA project, Ascend enables existing airport staff to identify the current risk level, define protective safety measures, and the current needed operational requirements. Additionally, the DRAMA solution equips airports with the tools to monitor the risk over time and adapt mitigation strategies as the risk evolves.

Furthermore, all airports are under pressure due to the COVID19 pandemic. As a result, they need to implement cost-effective, compliant solutions to manage drone risk. This solution is what Ascend is offering airports through the DRAMA project.

Users and their needs

Based on interviews with existing Ascend's customers, it appears that airports are being flooded with a wide range of drone detection solutions. Additionally, these solutions are of various quality and cost. However, drone detection systems currently offered to Ascend's existing customers in the aviation industry have an investment cost between € 250.000-5.000.000 with an estimated lifetime of 1-3 years depending on the industry development.

The monthly operation & maintenance cost is estimated to be € 2.000 – 100.000. The challenge is that many of the systems procured over the last 12 months have been purchased based on fear and political pressure rather than facts and actual needs since there is no defined standard for solving this problem. Additionally, many systems are designed for today's situation and ill-prepared for future development in the drone industry. The DRAMA project aims to change this situation.

Service/ system concept

The DRAMA solution is built on four elements directly related to the modules developed in this project.

Drone detection. To assess the drone activity in and around the airport area and collect the data foundation for the risk assessment, DRAMA uses the Ascend Radar and the COTS RF sensors. The Ascend radar is a primary radar; it is possible to track targets independently from their RadioFrequency signal by including this system.

Risk assessment. The risk assessment is the foundation for the implementation of protective safety measures. The risk assessment process is delivered as-a-service, enabling the airports to monitor their airspace's risk of drone presence.

Operational requirements. The operational requirements are the system and infrastructure requirements needed to implement the protective safety measures against drone activity in the airport airspace. The airports must be able to build an internal business case based on the risk assessment.

Protective safety measures. These measures are being put in place to mitigate risk when assessed to be too high. If the probability of a collision is low and the potential outcome is acceptable, no protective safety measures would be implemented.

Space Added Value

DRAMA is built on top of the outcomes from both AMMO and WAMMO activities; this means that many existing systems are reused in the new project. Space assets are GNSS data and satellite imagery. They are playing the following role in the DRAMA solution:

Visual identification in up-to-date satellite images is already used in Ascend's Wildlife modules to identify wildlife habitats, perform ongoing monitoring. This is used as up-to-date visual complementation in the drone activity analysis and user reports.

Positioning using GNSS is used directly in DRAMA to position drones and in real-time registration with the tablet application. The Ascend field app can be used with all modern smartphones or tablets and uses the GNSS receiver in the device to record the activities' positioning.

Classification and Temporal monitoring of satellite images. By continually monitoring satellite images from the areas around the client airports, seasonal and periodic values can be assigned to monitored areas. By assigning temporal values to drone risk areas, it will, to a degree, be possible to plan the effort needed in drone management in the upcoming period.

Current Status

The DRAMA project kicked off on 4 January 2021.The first milestone is the Baseline Design Review and is set for June 2021.
