Fundamentals of GPS Threats


How the growing threats to satellite navigation signals can impact your critical systems, and what to do about it.

GNSS Vulnerabilities-01

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.

This white paper is for people responsible for understanding the risk factors affecting GNSS-reliant systems, and for ensuring that appropriate steps are taken to mitigate them. In it you will find:

  • An introduction to the different threats to GNSS, and how these are evolving

  • Some guidance on evaluating the susceptibility of your systems to GNSS threats

  • An overview of some of the most effective techniques available to mitigate the risk of GNSS outages, errors and/or cyber-attacks on your critical systems

  • An introduction to Spirent’s GNSS threat assessment and mitigation services
