The core of SPEAR-EW’s payload is Leonardo’s advanced, miniaturized Digital Radio Frequency Memory (DRFM) technology, which offers the most advanced and future-proof electronic jamming and deception available on the market today.Powered by a turbojet engine the SPEAR missile offers over double the range, and a far more flexible operating envelope, when compared to a conventional glide weapon. SPEAR-EW utilizes this long endurance through its capacity to be launched at enhanced stand-off ranges and loiter while carrying out its jamming mission.
The LMADIS system comprises two all-terrain vehicles, called Polaris MRZRs. One serves as a command unit, while the other is outfitted with sensors and signal-jamming equipment. The sensor unit feeds information to a tablet on the command and control MRZR, from which an operator can track an incoming drone, get visual confirmation that it’s hostile, and disrupt communications between a drone and its home using a radio frequency blast.
The recent reports out of Syria highlight the inclusion of these in an evolving battlespace. One of the simplest threats to drones is the blocking or scrambling its reception of a signal from a GPS satellite. This “GPS signal jammer” can produce serious operational impact on military mission and will likely become more and more prevalent. According to a piece by NBC, Russians are using GPS jamming against the U.S. military’s smaller surveillance aircraft.
The Joint Improvised Explosive Device Defeat Organization, known as JIEDDO, funded the NERO project. The Project Manager for the Army's Unmanned Aerial System program collaborated with Naval Surface Warfare Center in Crane, Indiana, Raytheon and General Atomics to design and execute proper modifications to accommodate the jammer, and to operate the Gray Eagle aircraft.
The drone jammer are based on advanced digital signal processing technology with frequency jamming of global system for mobile, code division multiple axis and 4G band of cellular phones, an intelligence official said.They have deployed Pantsir S1 missile systems to Khmeimim airbase near Latakia to protected Su-57 fighters positioned there. The Pantsir combines short and medium range anti-air missiles on an integrated vehicle platform. At Khmeimim, the Russians have also setup a powerful GPS jammer whose effects can sometimes be felt as far away as Tel Aviv
