GPS jamming in US
The current US military 'Red Flag' training exercise is incorporating large-scale jamming of all forms of satnav guidance.
The largest ever such airborne exercise - based at Nellis Air Force Base, Las Vegas, Nevada - involves military aircraft from the US, UK and Australia, and runs from 26 January to 18 February.
A major aspect of the exercise is daily periodic denial of signals from GNSS and associated augmentation services (eg WAAS, GBAS and ADS). Jamming could take place each day.
The jamming will be centred at 37º28'N 116º04W, with possible GNSS denial within the following published range/heights:
- unlimited at and above FL400 (~40,000 ft)
- 447 NM at FL250 (~25,000 ft)
- 343 NM at 10,000 ft
- 338 NM at 4,000 ft
- 248 NM at 50 ft
Whilst jamming will test the military participants, it will also affect civil airborne and other users of GNSS for navigation and timing over a huge area . . it could be a relevant test for everyone.
