FlyingFish Products



FlyingFish Is a lightweight cost-effective Airborne Satellite (SAT) Monitoring System for the passive monitoring of Thuraya, Inmarsat and IsatPhone-Pro networks. The system will detect and intercept terminal and call activity within radio line of sight of the deployed system, including voice, fax, data and SMS (where available).

The main advantage of FlyingFish as an airborne system, is an increase in interception ranges > 400 Kms or 250 nms (altitude dependent) of the satellite terminal uplink due to better line of sight characteristics. FlyingFish can be deployed on vehicles, ships, towers, aerostats, and UAV’s. The use of any third-party decrypt connected to the system is subject to export license authorization.

Horizon Technologies sells its FlyingFish systems only to governments, and government-authorized agencies.

The FlyingFish operator is able to toggle between the appropriate software and appropriate antennae for either Thuraya, or IsatPhone-Pro networks. Monitoring of the two networks simultaneously is possible, but requires an additional demodulator unit. The system is capable of monitoring 32 duplex channels in Thuraya and IsatPro mode and 6 Duplex channels where terminals using the original ACeS Garuda satellite service.

FlyingFish customers can provide their own COTS downlink and uplink antennae. Horizon Technologies consultants can advise on appropriate specifications, and also can provide the complete system kits.

System Overview Modes of Operation
Used to passively monitor communications on the Thuraya, or IsatPhone-Pro networks, FlyingFish is completely passive and cannot be detected by either the mobile user or the satellite (SAT) network, making it ideal for covert operations.

Thuraya monitoring

For every event monitored on a Thuraya terminal, the GPS position of the originating terminal is recorded and its position can be displayed on an interactive map within the Graphical User Interface (GUI). This mapping functionality is based on the industry standard ArcGIS software produced by ESRI. Maps with finer detail and even satellite images can be incorporated into the interface. In addition to intercepting content from the L-band downlink side of the call, FlyingFish is also able to extract the channel assignment
for the matching uplink side of the call to intercept both sides
of the duplex call in full.

IsatPhone-Pro monitoring
In this system, a GPS signal is transmitted within the encrypted part of the call by the handset. Therefore, a third-party decryption unit is required to obtain content of the call and GPS position. The rest of the monitoring capability remains the same, with interception of both sides of the duplex call. FlyingFish can be used to intercept and monitor terminals using the original ACeS Garuda satellite service, or the Inmarsat IsatPhone-Pro service being operated through recently updated service for the Inmarsat’s I-4 EMEA or Asia-Pacific satellites. Recently (2014) migrated from the 4F2 to the Alphasat satellite.
