SAGE analyses the electromagnetic spectrum across the Land, Sea and Air domains in order to map the source of active emissions. Using highly accurate Direction Finding (DF) antennas, SAGE builds target locations and provides situational awareness, advance warning of threats and the ability to cue other sensors.

This state-of-the-art Electronic Support Measures(ESM) can be fitted to all platforms and configured to support a variety of requirements. Its favorable SWaP (Size, Weight and Power) characteristics allow it to be integrated with other sensors and missions systems, providing packaging opportunities on many platforms including small UAVs. SAGE eliminates the need for specialist ESM platforms, reducing cost and enhancing through its innovative SWaP with its dual role ESM/ Radar Warning receiver.
