Advanced and flexible GPS jammer

If we think of a cell phone as a hand-held two-way radio, radios can be interfered with, and cell phones are no exception. Like any radio, cell phone signals can be jammed.Jamming mobile phones is like jamming any other type of radio communication. A mobile phone communicates with its service network through a base station. As the phone user drives down the street, the signal switches from one base station to another.

Since increased power on a target normally provides more reliable suppression of the RCIED, reactive jamming is more effective in defeating high-power RCIEDs. However, as many RCIED transmission signals are at power levels below the resident EM environment, reactive jamming must be coupled with active jamming to provide full coverage against an array of high- and low-power RCIEDs.

The AN/ALQ-144 IR countermeasures set is an always-on infrared gps jammer, providing protection against infrared missiles over a wide environmental range. There are multiple configurations available to complement small- to medium-signature helicopters.Compact, advanced and flexible DRFM GPS jammer for pod, pylon and multiplatform aircraft type on-board integration. The global proliferation of advanced ground and air based threat systems is increasing threat levels, reducing freedom of manoeuvre and giving potential opponents a significant Anti-Access Area Denial (A2AD) capability.

Yet Sun Valley, Idaho is in the heartland of North America, far from any international conflict zone. It is presumably under the firm control of domestic authorities with an interest in keeping GPS and other GNSS signals clear and uninterrupted. Whether the cause of the near-miss was a poorly communicated military exercise, a citizen with a jammer, or some other reason, has yet to be made clear.

Over on the LimeSDR CrowdSupply blog, Ogün Levent has submitted a short article about his “Dronesense” project. Dronsense is a spectrum-scanning and GPS jammer system based on the LimeSDR. The LimeSDR is a US$299 12-bit TX/RX capable SDR that can tune between 100 kHz – 3.8 GHz, with a maximum bandwidth of up to 61.44 MHz.
