The Ministry of Defence conducts occasional tests on military systems, which may result in some loss of service to civilian users of the Global Positioning System (GPS) including in-car navigation devices and networks which rely on GPS signals.
Ofcom seeks to provide citizens and consumers with information about possible interruptions to these services. It must be emphasised that this notification process only warns of future jamming exercises that are brought to the notice of Ofcom and may not cover all jamming exercises. It cannot be assumed that any loss of service is due to jamming exercises.
If you have any queries regarding these notices, please forward them to InfoGPS.Notices@ofcom.org.uk
