Big Spectrum Capability for Small Teams

EMSO MASTER™, with its CRUMBCATCHER™ mission suite, helps your small teams pull information from vast amounts of radio frequency spectrum. With one small kit, or a network of them, one or many users can perform a range of Electromagnetic Spectrum Operations (EMSO) missions to detect, classify, demod & decode, monitor, and locate signals of interest, anomalous transmissions, or unauthorized activity. Its streamlined, lightweight web browser-based interface provides multi-user access from any device with a browser, even over high-latency / low bandwidth C2 links.

Multiple Missions

Electromagnetic Warfare, Spectrum Management, and Spectrum Compliance missions are all supported through the onboard CRUMBCATCHER Electromagnetic Support (ES) suite. The optional CRUMBCATCHER Electromagnetic Attack (EA) suite supports jamming and other active missions.


Highly Portable & Extensible

From a tiny passive remote system to multiple man-portable, air store/pod, vehicle, and other platforms, EMSO MASTER supports many different missions. Military, Spectrum Compliance, Law Enforcement, and other agencies can benefit from the same core capabilities, with options to integrate agency-specific tools.
