ADA (smart antenna)
Advanced smart antenna
ADA (an abbreviation of adaptive antenna) is an advanced smart antenna, using multichannel controlled reception pattern antenna (CRPA),[1] designed for various platforms, including UAVs, planes and ships, manufactured by the MLM factory of the Israeli Aerospace Industries (IAI).[2][3]
The ADA enables vehicles, missiles and other platforms equipped with the smart antenna to navigate even when heavy jamming is conducted in order to block all reception of GPS and other GNSS signals. Using advanced techniques even very faint "good" signals are being extracted from the superposition of incoming waves that include noise and strong signals produced by the enemy (or friendly) jammers. These signals are then used (just like a regular GPS receiver) to triangulate the position and determine the GPS tune.
