GPS Jammers (SCL-300) are designed to jam the GPS (Global Positioning System) based navigational systems in a tactical battlefield. SCL-300 transmits adequate power radio signals to cut-off communications between GPS Receiver and Satellite stations, by jamming the signals in the operating frequencies of GPS bands. It does not interfere with any communications other than GPS within the defined regulated zone.

Upon activating the Jammer, all idle GPS receivers will indicate "NO SERVICE". When the Jammer, is turned off, all Global Positioning System receivers will automatically re-establish communications and provide full service.

SCL-300 (GPS Jammers) provides suppression of the standard GPS receiver in an area of 1.5-50 km radius or more depending on the way of application of a Jammer, area relief and GPS terminal placement (on aerial or terrestrial objects).

GPS Jammers can also be used in Meeting Rooms, Conference Rooms, Museum, Gallery, Theatre, Concert Hall, Church, Temple, Restaurant, Class Rooms, Training Center, Factory, Bank, Train, Bus etc.

SCL-300 is a modular device which consists of three separate transmitter modules works in the frequency range of 1100 to 1230 MHz (Military Global Positioning System), 1230 to 1350 MHz (Military GPS), and 1520 to 1580 MHz (Commercial GPS). Total power output of the jammer is more than 25 watts.

GPS receives low-level signals from the satellite, which can be jammed by a ground-based jammer.

The equipment is employed primarily to jam the GPS based navigational systems in a tactical battlefield.

The jammer is able to render the GPS services ineffective or introduce unacceptable errors in their accuracies.
