FASST 6000 Spectrum Sensor
Next Generation RF Spectrum Sensor
FASST 6000
The Fastest Spectrum Sensor On The Market

Decisive SIGINT Advantage in an Ultra-Low SWaP Form Factor
When integrated with the StreamCaster MANET mesh network, FASST 6000 delivers the real-time situational awareness warfighters need to dominate contested environments. Available as a rugged handheld unit for dismounted operators or an OEM module for integration into unmanned systems, this ultra-low SWaP system packs the power of a much larger device into a tactical form factor, allowing operators to reprogram scan parameters on-the-fly to maintain a decisive edge in signal intelligence.
What is FASST?
FASST (Filtering by Aliasing Spectrum Sensing Technology) is a groundbreaking, proprietary RF signal processing technique that enables the sensor’s capabilities, delivering industry-leading spectrum scanning speed of 144.5 THz/sec. This allows FASST 6000 to perform near-instantaneous measurements from 1 MHz to 6 GHz across multiple coherent antenna ports, enabling detection of even extremely short-duration, low-power, or low-duty-cycle RF transmissions.
FASST 6000: Powerful Spectrum Intelligence at the Tactical Edge
Higher probability of detecting, intercepting, exploiting, and geolocating RF emitters
Delivering unprecedented scanning speed and precision in a compact, rugged form factor, FASST 6000 empowers operators with a higher probability of detecting and localizing threats to help deliver decision dominance on the modern battlefield.
FASST 6000 outperforms much larger, heavier, and more expensive systems that require more power to operate, effectively delivering the capability of a rack mounted SIGINT collection system in the palm of your hand.

Advanced DF and Geolocation for Real-Time RF Spectrum Intelligence
FASST 6000 is capable of high-speed spectrum scanning, signal detection, recording, and direction finding (DF). When paired with a DF antenna head, it provides accurate line-of-bearing to RF emitters, and with three or more networked sensors, enables real-time triangulation for precise geolocation. From dismounted SIGINT and airborne counter-UAS ELINT operations to wide-area distributed RF monitoring, FASST 6000 empowers users to realize a common operational picture across the electromagnetic battlespace.
Millisecond-Level Detection with On-the-Fly Control
In its default operating configuration, FASST 6000 can detect single-millisecond transmission events, while allowing users to dynamically reprogram parameters such as dwell time, scan speed, instantaneous bandwidth, and RF bands of interest. Native IP and USB interfaces, combined with embedded processing, allow for rapid deployment as either a standalone asset or a component of a larger distributed sensing architecture.
Unmatched Speed in a Tactical Form Factor
With a scanning speed of 144.5 THz/sec, FASST 6000 is the fastest spectrum scanning sensor on the market, outperforming competing systems by more than 100× while remaining significantly smaller, lighter, and more cost effective. This unique combination of speed, size, and effectiveness makes FASST 6000 ideally suited for dismounted troops, mobile platforms, and small unmanned systems operating in dynamic and contested RF environments.
