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™)

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.

  • Hosted in General Atomics Aeronautical Systems, Inc. SPIDI pod
  • Flight tested and currently flying
  • Only full spectrum SIGINT capability available for Predator B
