Global Navigation Satellite Systems Engineering, Policy, and Design
In the past few months, there have been articles in the press providing information and misinformation in advance of the GPS week rollover that occurred on April 6. Readers were warned to retire obsolete receivers, update software, check with manufacturers, and even perform testing of critical devices.

Hostile cyber operations such as jamming and spoofing of GNSS signals are a growing concern. While they do not cause major damages to the satellite navigation system as such, they can have severe effects on critical national infrastructures and many other systems. Here, we address how international telecommunications law as well as the international law on the prevention of war apply in this context.

Improvements to GPS performance are often incremental, achieved by squeezing better performance out of existing systems with clever tweaks, smarter analysis and sharper receivers. Then again, every once in a while, there’s a huge leap in the capabilities of the system itself—an advance so big that it makes you appreciate all over again the elegant wizardry of satellite navigation.

The Department of Homeland Security (DHS) has designated positioning, navigation, and timing services (PNT) a “National Critical Function.” That is PNT is now officially a capability so vital to the United States that its “disruption, corruption, or dysfunction would have a debilitating effect on security, national economic security, national public health or safety.”
