The ultimate objective of any TLS search is the rapid elimination of the interfering signal that is degrading the capacity of your valuable satellite assets. An essential step in this process is the positive identification of the offending uplink terminal. In most cases, localizing the interference source to a small geographic region and correlating this information with satellite user databases can accomplish this objective. Sometimes, however, even the most precise location ellipse will not allow positive identification.

Enter TLS FINAL SEARCH™—an aerial search of the position ellipse that positively identifies the specific antenna causing the reported interference.

Using the position ellipse provided by the TLS Model 2000, a helicopter or other aircraft carrying FINAL SEARCH receiving equipment conducts a systematic search of the designated area. With careful selection of the search altitude, the beam from even a relatively large antenna is sufficiently wide enough to fly through while following a predetermined search grid. The TLS expert selects the search altitude and search grid using all available information—including the expected antenna azimuth and elevation based on the satellite location, the signal strength in the adjacent satellite, and aviation-related factors such as airspace control issues, local traffic patterns, proximity to nearby airports, terrain, and weather.

FINAL SEARCH equipment ultimately identifies the offending transmitter antenna—including its street address—so that the antenna owner can be contacted and the interference problem resolved.
FINAL SEARCH is the ultimate defense against satellite interference. Since implemented in 1994,
it has never failed to locate the interfering transmitter.
