GPS Threat Mitigation

GPS vs. GNSS: Understanding PNT Satellite Systems

A GNSS, or Global Navigation Satellite System, is a generic name for a group of artificial satellites that send position and timing data from their high orbits. The GPS, or Global Positioning System, is just one of the many different sets of satellites that can provide such data.

Most satellite navigation systems operate on similar principles. The satellites are arranged in geosynchronous orbits – Each one's speed and altitude is carefully controlled so that it stays in the same place in the sky.

GPS Threat Mitigation - Why Network Time Users Should Care

Whether you use GPS to maintain accurate UTC for your facility's IP-enabled security system or you simply employ it to keep your distributed scientific control and testing systems synced up, you can't afford to succumb to an unexpected threat. From hackers and unwitting smart device users to regional atmospheric conditions and once-in-a-lifetime solar weather patterns, the world can be a risky place for those who depend on network GPS timing.
