Measurements for verifying GPS-jamming at RFN Vidsel

This report describes the tests performed in October 2011. The aim with these tests is to verify that no commercial GPS-receiver is jammed outside the flight restriction area Vidsel R02, when GPS-jamming tests are performed at RFN test range. It is shown in the report, by a combination of measurements and basic wave propagation theory, that two jammers at site Tore and Gustav simultaneously can jam without severely harm civilian receivers outside R02 with the following signals.  2 MHz bandwidth Filt-CA and 3 W.  4 MHz bandwidth PRN2 and 6 W.  20 MHz bandwidth Filt-P and 20 W.  40 MHz bandwidth PRN20 and 30 W.
