RFeye Node Plus 100-18 overview
The RFeye Node Plus 100-18 is a high-performance spectrum analyzer and monitoring receiver designed for fast, long-distance data transfer via a 10 Gigabit Ethernet SFP+ port, supporting both fiber optic and copper connections. It covers a tuning range of 9 kHz to 18 GHz and features edge processing for full 100 MHz instantaneous bandwidth (IBW) recording, capture, and streaming. With a 120 dB dynamic range, 390 GHz/s sweep speed at 2 MHz RBW, and best-in-class frequency accuracy, tuning time, and phase noise performance, the sensor delivers exceptional RF sensing capabilities.
The RFeye Node Plus 100-18 supports full 100 MHz RF recording (I/Q capture), allowing operators to analyze wider bandwidth signals. With enhanced processing power and memory, it manages and streams I/Q data at 550 MB/s (4 Gbps), making it ideal for advanced signal detection and high probability of intercept (POI) in EMSO, SIGINT, COMINT, DF, and EW missions. As an excellent handoff receiver in a networked system, it excels in spectrum monitoring, direction finding, and geolocation.
The RFeye Node Plus 100-18 delivers an optimal balance of SWaP-C and edge performance. Equipped with a high-speed processor, 10GigE SFP data interface, SSD port, and PCIe OCuLink port, it enables advanced RF intelligence capture and sharing, including full 100 MHz streaming via VITA-49. Geolocation streaming supports standard Asterix and Google Protocol Buffer data formats. Built for rugged environments, the sensor comes with a range of Control PC options.

RFeye Site software
Multi-mission, multi-domain and multi-user Connect to and task RFeye hardware with multiple missions simultaneously. Run multiple missions (geolocation, detection, measurement missions etc) in parallel for maximum flexibility. Spectrum monitoring & measurements Conduct ITU-compliant spectrum monitoring and all essential measurements including channel occupancy, power, and frequency deviation. Overlay and analyze with customizable charts and measurement tools. Signal Discovery Signal Discovery increases probability of intercept for hard-to-find, unknown signals, or signals hidden in the noise. It is especially useful to discover non-standard signals, drone telemetry and datalinks, and mesh modems, which help identify mesh networks. Fast, accurate geolocation Manually or automatically detect signals of interest and geolocate the source by using multiple geolocation techniques. Time Difference Of Arrival (TDoA), Power On Arrival (PoA), Angle Of Arrival (AoA) techniques are all supported as well as hybrid geolocation which combines all of them, displayed within the interactive map. Geolocate multiple targets over wide areas in real-time with extremely fast update rates ensuring accurate geolocation of emissions even from fast-moving targets. Hybrid geolocation draws on powerful algorithms, fast and accurate synchronised techniques (AoA, TDoA and PoA) for advanced localization and geolocation. The post-processing TDoA feature allows geolocation of recorded signals allowing, for example, post-event diagnosis of interference incidents. Geolocation scenarios can be conducted with the simulation tool enabling users to practice and fine-tune their geolocation and interference-hunting skills.
RFeye Mission Manager software
Mission Manager is a virtual spectrum manager, enabling users to establish and coordinate multiple scan operations, including sweep, occupancy, time, bearing, detector, and remote recording. Additionally, it permits sweep and interlinked surveys to form a command center from a central location. Software users can build a continuous and synchronous view of the spectrum as events happen.
