GPS jamming all week
A MoD exercise will see intentional jamming of GPS throughout this week, 26-30 April.
Multiple land-based jammers will be based within 5 km of 522900N 0004500E - Stanford Training Area in East Anglia.
They will be operated anytime between 0800-1700Z from 26 to 30 March 2012.
Predicted coverage of the 10 watt jammers is dependent on receiver height and directional sector from the source. Below is an indication of ranges at which a receiver tracking L1 C/A-code GPS signals would fail if the jammers were at max power:
- at ground level - 13.5 NM to N and 2.7 NM to S
- at 5,000 ft - up to 40.5 NM to N
- at 10,000 ft - up to 24.5 NM to N
- at 20,000 ft - up to 46 NM to N
- at 40,000 ft - up to 54 NM to N
The CAA reminds aviators that they should be prepared for erroneous readings of GPS and must carry reversionary means of navigation.
