ISAT INTERCEPTION SYSTEM

ISAT INTERCEPTION SYSTEM

Stratign offers two types of solutions (Tactical and Strategic) for interception of ISAT communications similar to the Thuraya Interception System

Inmarsat plc. is a British satellite telecommunications company, offering global, mobile services. It provides telephony and data services to users worldwide, via portable or mobile terminals which communicate to ground stations through 14 geostationary telecommunications satellites. Inmarsat’s network provides communication services to a range of governments, aid agencies, media outlets and
businesses with a need to communicate in remote regions or where there is no reliable terrestrial network. Whilst most Isat communications are the extensive geographical coverage provided by this network makes it more favoured by subversive and criminal groups located in remote regions or those wishing to avoid fixed wire network interception. This increased usage of the network by Anti-national elements for subversive activities due to its near global coverage necessitated the development of a system which can effectively intercept all communications over the Isat network.

1. Tactical ISAT Interception System
Stratign’s Tactical ISAT Interception System is designed to intercept ISAT Phone traffic (Voice and SMS) from AceS, Isat Phone, and ISAT PhonePro. The system provides duplex call by interception of both Uplink and Downlink at L-band. Tactical ISAT Interception System consists of two directional antennae, one for downlink (reception of the satellite signals) while other for Uplink (reception of uplink signals from ISAT Phone to Satellite).
The system uses state of art technology for the reception, demodulation, and decoding of ISAT signals. Due to the line of site restriction, the system provides the duplex calls if the target is within the Radio Line of Site (RLOS) range of 20Km (when the uplink antenna is above the ground level and maintaining the RLOS condition). In non RLOS conditions with the ISAT handset, the system will be able to intercept simplex calls only (conversation from satellite to ISAT Phone).
Besides the ISAT interception system that effectively intercepts ISAT phone traffic, Thuraya Interception System and Iridium Interception System are two other robust solutions Stratign offers in the sphere of communication interception.
The system is completely passive and does not interfere with the normal communications and hence its presence cannot be detected. The ruggedized make and portability of the system make it ideal for quick deployment. The user-friendly GUI and simple system configuration significantly reduce the training time required for the operator.

Searchable Database
The recorded conversations can be searched from the database based on the intercepted call identity parameters.
Call Synopsis
The system has a unique field for adding call synopsis.
Intercepted Parameters
Intercepts and displays parameters such as Voice, SMS, and Fax, Spot beam ID, Date and time of call, TMSI, IMSI, IMEI, Telephone number of called party, Telephone number of the calling party, Call type (Voice or SMS or Fax), Direction of the call flow (Incoming Call or Outgoing call), Duration of call (With start time and end time).
On-line and Off-line Analysis Tools
It is possible to integrate Stratign’s analytical tools such as Voice Forensic System, Link Analysis, OSINT, etc.
2. Strategic ISAT Interception System
The Strategic ISAT Interception System has the capability of carrying out nationwide Interception of duplex communications over the Inmarsat network. The System monitors downlink signals from the satellite on L- Band (satellite to handset) and C-Band (satellite to primary gateway station). By doing so, the limitation of duplex interception only up to RLOS distance in Tactical ISAT Interception System gets taken care of. Since all ISAT calls are routed through the regional gateway stations, the L-band uplink from the handset to the satellite is routed on the C-band downlink to the regional gateway stations. So, principally we are monitoring one side of the communication from the location of the target and the other side of the communication to the regional gateway station. Both Uplink and Downlink sides of the calls are then paired by the system to produce a full duplex (both sided) call. The system will be able to monitor up to 4 regional spot beams simultaneously, however, in case the country is vast and is covered by more than 4 spot beams, additional L-band monitoring stations can be deployed and integrated with the main system.
