Signals Intelligence (SIGINT) Systems

L3Harris provides world-class signals intelligence (SIGINT) systems, using scaled SIGINT technology developed over the past 60 years and leveraging decades of investment and experience. As a premier SIGINT systems developer and integrator of airborne ISR platforms, our capabilities are vertically integrated for quick-reaction support.

Capabilities

Multi-domain SIGINT – aperture-to-enterprise solutions
Processing, exploitation & dissemination
USAF DCGS Common Intelligence Collection System
Airborne, ground-based, manned and unmanned SIGINT payloads and podded SIGINT solutions

Integrated Solutions

Within the airborne domain, we are focused on both medium-altitude and high-altitude capabilities. Current integrated applications are available ranging from business jet class Strategic Airborne ISR to small, manned aircraft as well as unmanned aircraft.

Integrated on-board your platform for dedicated SIGINT and multi-INT configurations
Enables integration of larger systems
Supports multiple onboard and remote operators via satellite or line-of-sight communications

Scalable Open Architecture Reconnaissance (SOAR™)

SOAR integrates industry-leading, full-band SIGINT capability with a medium-altitude, long-endurance Predator B wing-mounted pod, offering unparalleled options for warfighters in the ISR domain. A new dimension for remotely piloted aircraft, SOAR provides significant mission expansion for Predator B operations against threats in new operating domains.
