RFeye Node 100-18-LW overview

The RFeye Node 100-18 LW (lightweight) sensor provides electronic warfare capabilities and RF intelligence in a compact, low Size, Weight, and Power (SWaP) package. Weighing 1.98 kg (excluding antennas), this intelligent RF sensor excels in signal detection, spectrum monitoring, and RF signal recording (I/Q data), capture, and geolocation up to 18 GHz.

The sensor is suitable for various UAS platforms, including those with small, medium, large, and very large Maximum Gross Take-off Weights (MGTW). The RFeye Node 100-18 LW's reduced weight extends UAS flight time, enabling high-performance electronic warfare (EW) sensors to be used as payloads on fixed-wing UAVs, large and medium-sized rotary drones, and tethered drones. Additionally, it can be integrated into unmanned ground vehicles (UGVs).

Three RF ports support antennas for different frequency bands and all four GNSS satellite constellations. Co-engineering, interference, and filter settings knowledge and support are available for airframe system integrators.
