"Fundamentals of GPS Threats": Discover how the growing threats to satellite navigation signals can impact your critical systems, and what you can do about it - White Paper
Satellite navigation signals from space are precariously weak and can easily be blocked, damaged, or compromised by a growing array of threats - including solar activity, man-made interference, malicious faking of GPS signals, and the manipulation of position and timing information. As we come to rely more and more on GNSS signals and data across a wide range of industries, understanding and mitigating against these threats will become a critical risk management activity for manufacturers, systems and applications providers, and end-users.
