SMS - SPECTRUM MONITORING SUITE FOR INTERCEPT AND DF APPLICATIONS

Overview

SMS (Spectrum Monitoring­­­ Suite) is a powerful and scalable software application specifically designed for Intercept and DF, radio spectrum monitoring and surveillance.

 

SMS can be successfully used in government, military and homeland security applications whenever it is necessary to detect, geolocalise, identify and analyse a radio emission.

 

Spectrum Managers can use SMS in order to detect and geolocalise a source of interference. For example, inside an airport where interferences can easily stop Air Traffic Control communications.

 

The advanced signal analysis features provided by SMS can fully support COMINT (Communications Intelligence) and SIGINT (Signal Intelligence) operations, in which a fast and wide band emission surveillance is required together with a high frequency resolution.

Architecture

SMS has a Client-Server architecture: the signal processing is performed on the server while the GUI (Graphical User Interface) runs on the client. Moreover, it is possible to distribute the signal processing on several computers in order to balance their workload.

 

Multiple computers running SMS can be connected through a network. Detected signals and Signals of Interest (SOI) can be transferred from one operator station to another in order to support network centric signal intelligence operations.

Operational workflow

SMS’s operational workflow is divided into three phases: Survey, Collection, Analysis.


Survey: scanning of the RF spectrum, detection of signals and estimation of the directions of arrival

 

Collection: extraction of the signals of interest (called alarms) from the detected signals, recording of the signals' parameters into the database

 

Analysis: demodulation, decoding and specific measurements of the signals of interest

 

SMS provides an extensive list of detection criteria (Survey phase) and alarm criteria (Colletion phase) reducing the operator workload and increasing system effectiveness.

 

Because all the alarms are recorded into the system database, it is possible to perform both on-line and off-line signal analysis.

 

In addition, SMS can be programmed to automatically tune one or more hand-off receivers onto specific alarms as well as transferring the alarm parameters to another SMS operator. This approach allows the setup of a radio monitoring network with operators having different roles (e.g. wide band analysis, narrow band analysis, communications transcription).

Radio monitoring ready to use configurations

SMS can be supplied as a stand-alone software application or integrated into a radio monitoring system.

 

RMS-DF-X is a radio monitoring system (Intercept and DF) based on SMS.

In accordance with English and Italian law it may be necessary for LOG.IN to obtain an export license from the Export Control Authority.

 

LOG.IN does not expect any difficulties in obtaining the export license but the final response can only be given from the authority after the system configuration, the content of the service and the End Customer have been clearly identified.
