Reliable Long-Range Multi-Link Communication for Unmanned Search and Rescue Aircraft Systems in Beyond Visual Line of Sight Operation

This article proposes and evaluates the concept of combining multiple cellular networks for highly reliable communication with those aircraft systems. The proposed approach is experimentally validated in several unprecedented large-scale experiments in the maritime context. It is found that in this scenario, conventional methods do not suffice for reliable connectivity to the aircraft with significantly varying overall availabilities between 68% and 97%.

Supporting Maritime Search and Rescue Missions through UAS-based Wireless Localization

The specific challenge addressed in this work is to analyze the proposed localization method under realistic conditions.

Enhanced UAV Indoor Navigation through SLAM-Augmented UWB Localization

Augmenting and fusing state of the art ultra-wideband (UWB) localization with monocular simultaneous localization and mapping (SLAM) to enable autonomous flight in areas not covered by wireless localization.

Scalable and Precise Multi-UAV Indoor Navigation using TDOA-based UWB Localization

The specific challenge addressed in this paper is enabling novel applications with autonomous UAV systems through tight integration with scalable and precise receiver-side time-difference of arrival (TDOA) based ultra-wideband (UWB) indoor localization.

Design of an UWB Indoor-Positioning System for UAV Navigation in GNSS-Denied Environments

This paper discusses the design and evaluation of a practical and cooperative UWB positioning system using newly available integrated radio frequency hardware and antennas.
