Jamming of GPS signals is taking place daily from a military training base in Norfolk.

Since 11 February, the GPS signal jamming trial has been centred on the Stanford Training Area (STANTA), 523230N 0004352E - 7 miles (11 km) N of Thetford and 25 miles (40 km) SW of Norwich.

A notice to airmen (NOTAM) explains that jamming may affect aircraft up to 40,000 ft within a radius of 30 NM, possibly affecting ‘airborne electronic situational awareness’ devices and unmanned aerial vehicle (UAV) links, giving intermittent or total failure or giving incorrect notification.  The jamming could also affect local vehicle traffic.

Jamming covers 433-915 MHz and 2.4-5.8 GHz. It could last up to 2 minutes at a maximum of 5-times per hour between 0900 and 2100 UTC.  The last day of the trial is 10 March 2019.
