Aviation resilience to GNSS frequency jamming and cyber threats.

R&D case: Resilience to GNSS frequency jamming and cyber threats (AIRING)

The challenge

The AIRING project has investigated the increased risk of interference and spoofing for aviation, and the technical ways it can be detected or mitigated. A concept was proposed to combine technology and operational procedures, in such a way that GNSS interference can be detected and dealt with in an effective and safe way.

The solution

A wide range of technological solutions for interference detection and mitigation was investigated, ranging from simple and readily available filtering techniques to complex, new antennas that cannot (yet) be applied on civil aircraft. The technologies were integrated in a detection and reporting concept. An operational concept was proposed to integrate the solution into current ATC practice.

What did we do?

NLR has investigated the use of a controlled radiation pattern antenna for civil aviation. The complex, multi-element antenna enables both detection and mitigation of GNSS interference and spoofing. The impact of AIRING technologies

on ATC operations was investigated in an operational demo with the tower (NARSIM) and cockpit (APERO) simulators, to show that the concept can reduce the operator workload and increase safety.

R&D case: Enabling temperature control for large scale additive manufacturing

The challenge One of the main challenges of Large Scale 3D printing of high temperature thermoplastics is the control of the interface temperature – which determines the degree of bonding between consecutive layers. When the deposited material has cooled down in excess, poor adhesion is achieved between layers, leading to insufficient strength, delamination, cracking and […]

R&D case COCOLIH2T - Composite Conformal Liquid H2 Tank

The global aviation industry is committed to reducing global net aviation carbon emissions by 50% by the year 2050, with the European Commission pursuing a more ambitious goal of a 75% reduction in CO2 emissions per passenger kilometre. Alternative fuels such as liquid hydrogen (LH2) are seen as playing a central role in a zero-emission […]
