TEL AVIV — Israel Aerospace Industries (IAI) will debut at the upcoming Aero India exhibition in Bangalore an export-approved system to defend against GPS jamming.

Called ADA after the special adaptive antennas developed by the firm’s MALAM division, the system is operational in Israel and is slated to be installed in yet another Israeli Air Force manned platform in the coming months under a contract estimated at “tens of millions of dollars,” IAI executives said.

Measuring about 20 centimeters by 20 centimeters, the laptop computer-sized system is based on the firm’s multichannel Controlled Reception Pattern Antenna [CRPA] technology designed to render avionics systems immune to direct electronic attack from GPS jammers or other methods of interference. The system consists of two major elements: a GPS antenna array built from multiple antennas and an advanced digital processing unit.
