Spectrum surveillance can identify and geolocate suspicious transmitters and jammers and help fight crime

The functioning of modern societies is highly dependent upon wireless communications. Much of our economic activity relies on GPS systems which are particularly vulnerable to failure, disruption and interference. The possible consequences of GPS not working range from the inconvenient (not being able to use your satnav), through risks to public safety (interference with air traffic control), to possible loss of life (interruptions to emergency services communications).

Police forces have established a strong correlation between use of jammers and criminal activity. Criminals use jamming equipment to disable GPS signals when trying to steal cars and trucks with GPS protection. They may also use jamming techniques or irregular mobile transmissions to evade detection and conceal weapons- or drug-related criminality. The ability to detect and pinpoint the source of jamming equipment, and identify suspicious patterns of transmission, can greatly aid police and security services in the fight against crime and terrorism.

RFeye can help in this fight. Strategically located networks of fixed or mobile RFeye receivers can sweep the spectrum environment at high speed to detect suspicious transmissions and interference. Direction finding techniques, including AOA, TDOA and POA, can be used to pinpoint rogue transmitters in real time enabling police or security services to investigate.
