DESTINATION

system of a satellite communication with their subsequent registration and processing

THURAYA 2/3 coverage

FEATURES

 Search of accessible beams for monitoring in a reception point

 Reception and processing physical channels in directions

"subscriber-satellite" and "satellite-subscriber"

 Primary processing of the received digital signal (extraction of data

packages, demultiplexing, removal of scrambler, deinterleaving, removal convolutional codings)

 Identification of head and terminations of session

 Automated classification of messages by kinds of the traffic (a fax,

data, speech, SMS)

 Registration of session messages on hdd in database

 Selection in a database of records about sessions on multiply

conditions and parameters

 The further session processing with a view of gathering statistical

data

data from the block of decoding;

• Decoding unit provide:

 Reception of the coded data from processing unit;

 Determination of structure of the optimum decoder;

 Decoding of data according to the chosen algorithm;

 Sending of the decoded data on the block of processing of signals

• File-server/Database server provide:

 Storage of session data;

 Registration of acting data on sessions in a DB;

 Management of records of a DB on the basis of SQL inquiries

• Automated workstation of session processing provide :

 Information processing of input messages;

 Formation of reports under the processed information

• Automated information display workstation provide :

 Information processing about the location of a radiation source;

 Source display to cartographical model

 The quantity of an automated workstation in structure of a system can be increased depending on information loading processable

channels and requirements on efficiency of monitoring for incoming messages

 Types of session messages on which monitoring is conducted:
