Qinetiq (Hall 2, J13/4) has sold five of its satID satellite geolocation systems this year, worth a total of $3.6million. The system identifies and locates the source of interference to satellites within minutes - typically to within 10km.

It is the culmination of more than 20 years of research into geolocation by Qinetiq. It can be deployed using existing satellite communications infrastructure, on a worldwide basis.

Levels

The company offers three levels of geolocation service. Customers can purchase an entire system, enabling them to pinpoint sources of interference wherever and whenever necessary.

They can ask Qinetiq to bring its portable Fly-Away version of satID to their location to investigate the problem, or Qinetiq can use its own systems to provide a geolocation service covering Europe and the Far East.

Buyers include the US Department of Defense (DoD) which has bought one satID and is planning to purchase two more systems after a technical evaluation of its merits.

Interference is usually accidental - the result of faulty equipment, or incorrect operation of ground terminals.

However, malicious interference does occur. During the 2002 football world cup, members of a religious group jammed Chinese satellite TV broadcasts.
