A small jammer on this cliff-top disrupted GPS on vesselsout to ranges as wide as the Dover Strait

Low-powered GPS jammer on ship

Jammer of less than 1 milliWatt: •False positions, and velocities •Autopilot may turn vessel•But no alarms!

With a little more jammer power:•Electronic Chart Displays•Autopilot•Automatic Identification System•Differential GPS•Satellite voice and data comms•Maritime distress safety system

plus …Ship’s Radar & Gyrocompass

Jammers like this on our streets can block all frequencies ofGPS, GLONASS, Compass-Beidou and Galileo, plus theQZSS, GAGAN, WAAS and EGNOS augmentation systems.

Frequency bands shared bymultiple GNSSS transmissions

Jammer’s spectrum affects GPS, Galileo, Compass and GLONASS
