Analysis of 5G and LTE Signals for Opportunistic Navigation and Time Holdover
Winter, Adrian; Morrison, Aiden J; Sokolova, Nadezda (Peer reviewed; Journal article, 2023)The purpose of this study was to evaluate the stability and therefore suitability of available fifth generation (5G) and long-term evolution (LTE) signals for positioning navigation and timing (PNT) purposes with particular ... -
GNSS-Denied Navigation using Direction of Arrival from Low-Cost Software Defined Radios and Signals of Opportunity
Winter, Adrian; Sokolova, Nadezda; Morrison, Aiden J; Johansen, Tor Arne (Journal article, 2022)This paper describes a novel navigation system for outdoor navigation in conditions where reliable satellite navigation cannot be assumed. It is build around inexpensive of-the-shelf hardware and could be used with several ... -
Lightweight UAV payload for image spectroscopy and atmospheric irradiance measurements
Hasler, Oliver Kevin; Winter, Adrian; Langer, Dennis David; Bryne, Torleiv Håland; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)This paper presents a low-cost lightweight UAV payload for remote sensing purposes using a small imaging spectrometer made from COTS components. The novel design with an additional upward-facing spectrometer allows for ... -
Low Cost Collaborative Jammer Localization Using a Network of UAVs
Ahmed, Naveed; Winter, Adrian; Sokolova, Nadezda (Peer reviewed; Journal article, 2021)Radio Frequency Interference (RFI), either intentional or unintentional in nature, can have significant impact on the performance of systems utilizing GNSS receivers. It can therefore be beneficial for a commercial autonomous ... -
Low-Cost Angle of Arrival-Based Auxiliary Navigation System for UAV using Signals of Opportunity
Winter, Adrian; Sokolova, Nadezda; Morrison, Aiden J; Hasler, Oliver Kevin; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)Many modern devices rely on satellite navigation for reliable, precise and ubiquitous localization. While this enables technological advances that have been unthinkable a few decades ago, it also has clear implications on ...
