RF DETECTION

The service delivers advanced maritime surveillance and vessel tracking by utilizing satellite-based RF detection. It captures and analyzes radar emissions(X-band and S-band simultaneously) from vessels to provide comprehensive monitoring.

RF DETECTION

UNSEENLABS

Unseenlabs delivers exclusive data by detecting radio frequency (RF) signals emitted by ships across vast maritime areas, and by geolocating and characterizing these RF signatures, it enables the monitoring of uncooperative vessels so-called "dark vessels" that evade traditional surveillance. Initially focused on the maritime domain, this unique space-based RF detection technology is now laying the groundwork for broader applications.

The Automatic Identification System (AIS) is the primary means of tracking ships at sea, yet it was not originally designed for surveillance and can be easily switched off or manipulated, creating challenges for governments, NGOs, maritime authorities, and marine insurers that depend on accurate data for security, enforcement, and risk assessment.

Unseenlabs delivers exclusive RF intelligence that surpasses the limitations of declarative systems and integrates seamlessly with existing land, sea, air, and space-based monitoring infrastructures, significantly enhancing intelligence and surveillance capabilities.
