FlyingFish™ 3rd Generation

The FlyingFish™ Airborne Satellite Phone Monitoring System is a proven affordable SIGINT solution
for manned and unmanned ISR platforms. It allows governments to passively monitor satellite communications.
FlyingFish™ is an idea adjunct solution for those countries possessing strategic SIGINT systems.
Can operate away from current L-band coverage, and together with airborne EO/IR, provides essential
“eyes on target” which is so crucial to today’s missions.

Benefits of Flying Fish™

FlyingFish™ is a proven Airborne Satellite Monitoring System designed to passively and simultaneously
monitor Thuraya and IsatPhone Pro networks.


The system will detect and intercept terminal and call activity within radio line-of-sight including voice, fax, data, and SMS. It provides remote L-band capability for those operators of strategic systems.  More than 50% of our users combine FlyingFish™ with current European or Israeli strategic SIGINT systems.  FlyingFish™ data is integrated seamlessly into current SIGINT databases.

Increased Interception Ranges

The main advantage of FlyingFish™ as an airborne system is increased interception ranges up to 400 km or 250 nm (altitude and environment dependent) of the satellite terminal uplink due to a better line of sight. FlyingFish™ can also be used for vehicular and shipborne applications.

Simultaneously Monitor Iridium, Thuraya and IsatPhone Pro

The 3rd Generation FlyingFish™ is able to simultaneously monitor Iridium, Thuraya and IsatPhone Pro SAT phones. The system is capable of monitoring a total of 96 duplex channels:  32 Thuraya channels, 32 IsatPhone Pro channels, and 32 Iridium channels

Integrated GPS/AIS Receiver

The system also incorporates an optional integrated AIS/GPS receiver for maritime applications. This is especially valuable for correlating AIS tracks with Sat Phone calls at sea. The receiver will be able to process AIS message formats defined within the internationally accepted standards for AIS equipment.
