IAI unveils Compact ADA: advanced defence against GNSS jamming

By Arie Egozi

Massive GNSS jamming was first encountered in Ukraine and, in recent months, in Israel, especially in the northern part of the country where the Hezbollah terror organization uses Iranian armed UAVs and cruise missiles to attack Israel.


Israel Aerospace Industries (IAI) has unveiled Compact ADA, offering reduced Size, Weight, and Power (SWaP), an advanced system that protects avionic systems from GNSS jamming.

The Compact ADA system maintains assured PNT (Position, Navigation, and Timing) by overcoming GNSS jamming, ensuring that tactical platforms can continue to operate with consistent GNSS availability. This is in contrast to most navigation, communication, and warfare systems which depend on the continuous availability of GPS/GNSS signals. However, cheap, low-end equipment can seriously degrade GNSS Position, Navigation, and Timing (PNT), even to the point of total solution denial.

IAI has over 20 years of proven experience in supplying a wide range of GNSS Anti-Jam solutions for the most demanding requirements. They also have vast experience in integrating immune navigation solutions into airborne (manned and UAV), surface, maritime, and guided munitions.



Compact ADA is a derivative of the ADA system adapted to air tactical platforms. The Compact ADA offers the benefits of the advanced immunity capabilities of ADA in tactical platforms. The ADA product portfolio, developed by IAI, is compatible with a broad range of satellite navigation systems (GNSS). Its state-of-the-art technology implements multiple mitigation methods and specialized digital signal processing algorithms. The system’s versatility facilitates integration into numerous platforms.

Jacob Galifat, General Manager of IAI’s MALAM Division, stated: “With the threats that GNSS faces today, these systems are a must for any platform using GPS or any other Global Satellite Navigation Systems. Our operationally proven systems ensure the availability of GPS and GNSS-based systems, even in the most contested, EW-saturated battle space. Considering the operational challenges, this system has considerable export potential for many air forces and armies who experience GNSS jamming in combat zones.”
