Forthcoming GPS jamming exercises

UK GPS users may find that their satellite navigation systems are disrupted and may not work at all during certain days in April, as the Ministry of Defence carry out a jamming exercise.

The aim of the GPS blocking exercises is to find out how interference could affect military personnel.
