The Chronos Technology CTL3500 interference monitor and GPS jammer detector is designed to detect the presence of too much GPS satellite power or non-GPS signal and interference broadcasting 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, 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 centre 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.
The device is also ideal for operations and support engineers to check GPS antenna installations. CTL3500 can check roof-top installations for interference from other sources and adjacent GPS antennas or determine if a GPS signal is being accidentally rebroadcasted from a poorly made or corroded cable, connector or antenna assembly.
