Satellite Identification & Location System determines the location of both known subscribers and unwanted interferers. Quick and accurate co-ordinates from SILS enable the satellite operator to target “where on Earth” to take action and mitigate damage to their service. We enable our customers to: maintain their satellite communication capacity, offer higher quality of service, lower subscriber complaint levels and identify where denial of service threats are located.

The multiple satellite location technique is based on the principle of simultaneous determination of the Differential Slant Range and Differential Slant Range Rate, which are determined by knowledge of the satellite position and velocity.

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

Measurement of Time & Frequency Difference of Arrival of the interfering signal is made through use of signals retransmitted by the interfered satellite and by an adjacent satellite, and received by two monitoring earth stations.
