Overview

Smaller Than A Tablet

Our Keris ESM solution is a compact, high-performance electronic support measure (ESM) sensor designed to detect, collect and characterize radio frequency (RF) signals across a wide frequency range. Its ultra-small size, weight and power (SWaP) design enables seamless integration onto small crewed, uncrewed, high-altitude and unattended platforms. Keris is a low-cost and dual-use system with a number of commercial and civilian use cases.

Mission Application

Keris small SWaP ESM system is designed for tactical, mobile and special operations where traditional, large ESM sensors are impractical. They are used across air, land and sea domains to provide radar detection, classification and geolocation for situational awareness and threat warning. Modes of operation include:

Scanning

Supports a variety of scanning modes to support JICD, automated search, fast scanning and staring 

Duty Cycling

System holds a state configuration file to allow for scans to be executed immediately at boot, across power cycle, etc.  
Internally managed power rails for remote battery powered operations and low-power modes 

Time and Position

Time and position from external or internal GPS Alternate Configuration 
Optional configurations including transmit features
