Israel’s IAI Unveils ADA-O Capability To Counter GNSS Jammers

Israel Aerospace Industries (IAI) is introducing ADA-O, an additional development in the Adaptive Antenna (ADA) lineup, which addresses satellite jammers to ensure Global Navigation Satellite System (GNSS) availability for land platforms. The land platform can be readily integrated in a range of capabilities, providing a unique operational response to helps telecom, navigation and command and control (C2) systems. Easily installed and integrated on the end-user platform, it serves end users on armored vehicles, artillery, C2 centres, and communication carriers.

In addition, IAI has recently won a contract to provide the ADA system to an Asia-Pacific nation in a contract estimated at tens of millions of dollars. The systems to be supplied will be mounted on a range of airborne platforms in the client’s various arms. IAI was chosen for this intricate project following a lengthy assessment process of the avionic integration and in-depth technical review of the ADA system performance. The win adds to other accomplishments scored by IAI’s MLM division, including MLM’s recent agreement with Honeywell for co-development of a jam-resistant Embedded GPS INS system (EGI), reinforcing IAI’s position as a national knowhow centre on GNSS anti-jamming systems.

Boaz Levy, General Manager and Executive VP of Israel Aerospace Industries (IAI) Systems, Missiles & Space Group, said, “ADA and its new derivative ADA-O for land platforms, is an important complement for every platform that uses GNSS receivers in general and GPS in particular and a vital tool for every modern army. Understanding the unique operational needs of land systems allowed us to perform the required modifications on IAI’s airborne Anti-Jam system so as to provide an advanced technological solution to the operational challenges facing the forces in the different platforms. We are proud to provide ADA and its derivatives to a range of customers worldwide; being confident ADA will provide full response to the challenges they face.”

In the beginning of 2017, IAI won an Israeli Ministry of Defence tender for the integration of anti-jamming systems in one of the key platforms of the Israeli air force. In this project, IAI provides the Israeli air force a comprehensive solution based on a multi-element antenna array, implementing Controlled Reception Pattern Antenna (CRPA) technology. The system’s integration allows the avionic systems that rely on satellite navigation to persist in their mission despite jamming or disruption attempts with GNSS jammers or other systems designed to block satellite navigation.

Most navigation, communication, and electronic warfare systems depend on continuous availability of GNSS satellites. Despite this dependence, the majority of avionics systems are not equipped with anti-jam capabilities and are vulnerable to disruption by low-power jamming emitters. The system developed by IAI supports multiple satellite navigation system constellations, feature an advanced architecture, and employs a range of advanced methods of digital signal processing. The system’s versatility makes it ideal for integration in a range of platforms including combat aircraft and helicopters, unmanned aircraft, land platforms such as tanks and armored vehicles, marine platforms, and guided munitions.
