Abstract
<jats:p>In the modern world, the intersection of zones of military conflict and wild-animal migration routes has created an unprecedented crisis in ecological movement studies. The escalation of armed conflicts in Eastern Europe and the Middle East has led to the widespread use of electronic warfare (EW) systems to suppress and spoof signals from global navigation satellite systems (GNSS). For researchers using GPS/GSM trackers to study ornithofauna, this has resulted in significant data loss, premature depletion of device power sources, and the appearance of false coordinates in datasets. This paper presents an analysis of the mechanisms of EW impact on telemetric equipment, examines the physical principles of signal jamming and spoofing, and proposes a comprehensive protocol for obtaining undistorted data. Particular attention is paid to hardware solutions and algorithmic post-processing methods. The goal of this document is to equip the scientific ornithological community with the tools needed to continue monitoring under a “noisy” radio environment.</jats:p>
