Communication Surveillance > Thuraya Monitoring System

 
Portable Solution
The portable solution is compact and easy to carry unit, which can be used to monitor the L-Band communication, taking place between the Thuraya Mobile Hand Set and Thuraya satellite. The Thuraya Monitoring system is designed to monitor both up-link and down link communications from the mobile handset. The Thuraya Interception system can be configured to receive from 1 - 16 Duplex Channel in a spot beam or the system can receive upto 4 full spot beam traffic.
System automatically scans the available spot beams and provides the spot beam ID, Latitude & Longitude of center of the spot beam, Channel Number. The Thuraya Interception system automatically tunes the demodulator to desired spot beam. Each demodulator can be individually tuned to different spot beams. The system monitors both forward and reverse channels simultaneously to provide the users with Full Duplex call Intercept.
The Thuraya Monitoring system has been designed to monitor and retrieve voice, SMS, Fax and data communication. The system comes with auto classification process which automatically detects and identifies the type of intercept i.e. voice, SMS, Fax and data communication. The system decrypts the voice, SMS, Fax and data communication almost in real time. Since the system monitors both Uplink and Downlink from the L-band, there is no need for huge C band antennas.
The Thuraya Monitoring system displays activity of BCCH, AGCH, PCH, BACH, FACCH, SACCH, SDCCH, and RACH. The system is also integrated to mapping tool (GIS MASTER) to provide geographic location of the suspect. The co-ordinates of the suspect are provided by the system and the same can be adapted to any GIS application, which the end user might have.
The portable system provides following details during the target interception:
Incoming and outgoing MES call numbers.
Type of encryption.
IMSI, TMSI, IMEI.
Type of MES (MES power class).
GPS time stamp.
Paging response.
Alerting response.
Type of terminal (fixed or mobile).
MCC and MNC.
Raw data before decryption.
Frequencies in use in the spot beam and in adjacent spot beams.
Call date and time.
Start time and duration of the incoming and outgoing calls.
Network channel and slot number.
Communication type (voice\fax\data).
Ciphering algorithm type and ciphering key sequence number.
TSI contents in fax call.

Thuraya Satellite monitoring
Fixed Solution
The system is designed to be deployed on static location. The system monitors both L-band and C-band communication of Thuraya networks. The system monitors the reverse channel communication of the Thuraya handset at the C-Band downlink of the Gateway Earth station and the forward channel from the downlink of L-band communication between the Thuraya handset and satellite. The system is a static rack based system, which can be configured to intercept up to 8 spot beams from one location. Multiple systems can be integrated to provide a full coverage of the target area.
System automatically scans the available spot beams and provides the spot beam ID, Latitude & Longitude of center of the spot beam, Channel Number. The system automatically tunes the demodulator to desired spot beam. Each demodulator can be individually tuned to different spot beams maximum 12 with one system.
System monitors both forward and reverse channels simultaneously. The system can monitor up-to twelve Spot beams at a time. The system can automatically map the uplink RACH control channel and the appropriate TCH channel at the C Band to appropriate L band downlink channel.
The system can automatically detect during O & M activities and can display activity of BCCH, AGCH, PCH, BACH, FACCH, SACCH, SDCCH, RACH.
As in the portable system here the static system is also integrated to mapping tool (GIS MASTER) to provide geographic location of the suspect.
