Israel Aerospace Industries (IAI) subsidiary Elta Systems has launched a new airborne software-defined radio (SDR).

Announced by IAI on 2 March, the ARC 840 SDR – Network Centric Operations (SDR-NCO) system is the latest in Elta's portfolio of military airborne communications that provides voice, video, and data communications.

Operating on very high frequency (VHF), ultra-high frequency (UHF), and L-band frequency ranges, the radio is interoperable with a wide variety of existing military and commercial radios, enabling aircrews to communicate with forces on the ground, in the air, and at sea, the announcement said.

Featuring a modular architecture, SDR-NCO comprises two user-swappable radio frequency (RF) modules that allow the user to tailor the frequency band combinations to suit different mission requirements. The radio is designed to support command and control, navigation, video sharing, and other network applications, according to the announcement.

The system also implements transmission security (TRANSEC) and communications security (COMSEC) frequency-hopping support as well as low probability of intercept (LPI) techniques to provide a high degree of security.
