摘要

Spoofing attempts are inevitable and must be detected and mitigated rather than eliminated. Adversaries can manipulate signal properties to induce spoofing. Identifying the key properties most affected by interference is crucial for early detection, ensuring the security of critical missions such as ground and aerial navigation. With this objective, this paper analyzes three key parameters of Navigation with Indian Constellation (NavIC) receiver, Pseudorange, Doppler, and azimuth-elevation for identifying spoofing occurrences before the Position, Velocity, and Time (PVT) solution is computed. This framework offers a proactive approach to detecting spoofing attempts and implementing countermeasures in advance. A small rectangular region with a perimeter of approximately 2.3 km within the Sardar Vallabhbhai National Institute of Technology (SVNIT) campus is selected to monitor discrepancies across all three parameters for NavIC and Global Position System (GPS) both. The results confirm that these parameters are effective early indicators of spoofing attacks, enabling the timely implementation of appropriate countermeasures to ensure secure and accurate navigation. This is especially crucial for NavIC-equipped UAVs, allowing them to detect spoofing a priory, reducing complexity, and saving time.
