GPS jamming exercises
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.
Dates: The exercise will run over the period 19 April 2022 and 21 April 2022
The jamming will be limited to 08:00 to 18:00.
Location: Jammers will be located at Salisbury Plain, within 4km of 51° 14' 11.4'' N and 2° 3' 7.2'' W
Frequencies: 24MHz bands centred on 1575.42MHz and 1227.6MHz
Area of effect in not expected to exceed the confines of Sailsbury plain training area, however it is possible but unlikely that sUAS operators and GNSS users may experience a denial of service (DoS) inside 5NM of 51° 14' 11.4'' N and 2° 3' 7.2'' W, up to altitudes of 1000ft.
