satID combats interference of communication satellites

Keywords: Communication, Satellites, Interference

satID, which locates transmitters that threaten the integrity of satellite communication channels, has been developed to combat interference problems with satellite communications traffic. The satID system developed by QinetiQ provides satellite operators and their users with the opportunity to identify and resolve satellite interference problems. The introduction of advanced satellite based services, the emergence of personal satellite communications technology and congestion of the geostationary arc are all increasing the regularity at which interference occurs.

"QinetiQ has undertaken over 20 years research into the area of geolocation, which has resulted in the delivery of interference location services and the creation of the system, satID", said Nigel Smith, Group Manager at QinetiQ. "The satID system provides satellite operators with the opportunity to maintain and enforce the integrity of their satellite communications systems. It can detect and locate unauthorised exploitation of satellite resources and interference resulting from human error, equipment failure or malfunction."

The satID system can be deployed using existing satellite communication equipment, on a world-wide basis.

The multiple satellite location technique is based on the principle of simultaneous determination of the differential slant range and differential slant range rate, and the subsequent application of the satellite position and velocity data.

Interference is determined from the results using the technique above that identifies the interfering transmitting site using two geostationary satellites, one of which is the interfered satellite.
