Due to the decrease in cost, size, and weight, unmanned aerial vehicles (UAVs) are
becoming more and more popular for general-purpose civil and commercial applications …

In the paper, we present results from flight trials conducted to investigate the characteristics
of the L-band air-to-ground radio channel for positioning applications. We discuss the …

In civil aviation, air-traffic management and with that the underlying communication,
navigation, and surveillance (CNS) infrastructure is currently being modernized. To test …

The paper investigates the variation of the received line-of-sight (LoS) power due to ground
multipath propagation for the L-band air to ground radio channel. Within, both theoretical as …

The presented work investigates a sparse Bayesian incremental automatic relevance
determination (IARD) algorithm in the context of multipath parameter estimation in a super …

In recent years, multiple antenna systems have demonstrated significant improvements in
communication system performance. However, little research has been conducted on their …

Abstract Unmanned Aerial Vehicles (UAVs) offer promising potential as communications
node carriers, providing on-demand wireless connectivity to users. While existing literature …

The future avionic navigation system is going to rely on the GNSS in the near future.
Because of the possible GNSS outage due to intentional or unintentional interference, there …

The process of verifying correct operation of terrestrial navigation aids for civil aviation
(NavAids) is based on flight inspection, which requires dedicated flights with specialized …

In this contribution, we present a method to analyze the effectiveness of multipath mitigation
by extended averaging in the context of terrestrial radionavigation. We derive the …
