LYDBROOK, England, 10 July 2009. Chronos Technology in Lydbrook, England, is introducing the handheld CTL3500 GPS Interference Monitor that detect too much GPS satellite power or non GPS signal and interference on the satellite navigation L1 channel, which could indicate inadvertent interference or intentional electronic warfare attacks intended to jam GPS signals.

The relatively low-cost, hand held, battery operated device uses low noise signal amplification with precision SAW filters and logarithmic detection to detect interference to GPS sensor signals. The filtering and detection techniques check for unwanted signals within the center of the GPS L1 band no matter what the waveform or modulation scheme may be and indicates the level on the 5 LEDs and cadenced vibrator.

for operations and support engineers to check GPS antenna installations, the CTL3500 can also check roof-top installations for interference from other sources and adjacent GPS antennas and check that the GPS signal is being accidentally rebroadcasted from a poorly made or corroded cable, connector or antenna assembly.
