Horizon Technologies’ BlackFish™ SIGINT system is our 4th generation airborne Sat Phone SIGINT system, and monitors the Thuraya, ISAT, and Iridium Sat Phone networks. Monitoring L-band Sat Phones is a key component of ISR missions, and Horizon Technologies’ BlackFish is small and light weight. It is fully DO-160 airborne qualified for the harshest fixed and rotary-wing airborne environments.

Tri-Band Sat Phone SIGINT System monitoring

  • Signal blue

    Simultaneously monitor Iridium, Thuraya and Inmarsat Sat Phones. Capable of monitoring a total of 50 duplex channels or 100 simplex channels.

  • Globe blue

    As an airborne system interception ranges up to 200 km or 108 nmof the satellite terminal uplink due to a better line of sight.

  • Target blue

    Complete mission software as standard which can be used to integrate BlackFish™ capabilities into any aircraft tactical mission system.

Horizon Technologies provides solutions for any user, and any environment.

Our BlackFish™ and legacy FlyingFish™ systems are deployed in the air, on land (vehicle mount), on towers, and on vessels. Even better, they can be networked into a single integrated system for geolocating and monitoring L-band Sat Phone traffic.

Our Amber™ space-based maritime intelligence data network provides geolocations and demodulated data from maritime L-band Sat Phones and datalinks, S and S band maritime radars, and AIS.

Blackfish is a proven system

Designed to passively and SIMULTANEOUSLY monitor Iridium, Thuraya, and Inmarsat (IsatPhone Pro) sat phones. The system will detect and intercept target terminals, and call activity within radio line-of-sight.

Blackfish hardware

BlackFish™ uses state-of-the-art technology and is based on a Software Defined Radio (SDR), equipped with powerful CPU and GPU processing capacity, a passively cooled system ensuring maximal reliability and performance. The system has no moving parts which ensures reliability during operation in extreme conditions.
