TLS: Your Reliable Partner for Satellite Interference Geolocation

TRANSMITTER LOCATION SYSTEMS, LLC provides you with an effective solution to satellite interference problems. Our established products and services help you quickly resolve costly and disruptive interference problems, before they reach the crisis stage. TRANSMITTER LOCATION SYSTEMS, LLC (TLS) is the only company in the world solely devoted to solving the complex challenges of satellite interference and unauthorized transponder use. Through a global network of advanced TLS geolocation receiving stations, TLS is strategically and uniquely positioned to help protect satellite assets around the world.

For over 25 years TLS's parent company, Interferometrics Inc., has supported mission-critical space, telecommunications, intelligence, and military operations with its internationally recognized scientists, advanced degreed engineers, and satellite systems experts.

Interferometrics’ technological contributions include the design and development of state-of-the-art systems in the fields of launch vehicle avionics, cellular telephone radiolocation, space-based high-resolution imaging, high-speed data acquisition and recording, high-precision satellite tracking, aviation safety technology, and the construction, launch, and on-orbit operation of microsatellites.

The company’s patented inventions include technology for precise radiolocation of cellular telephones, spatial location of cloud-to-cloud and cloud-to-ground lightning strikes near airports, passive satellite tracking, and multiple patents covering the TLS technology—which locates the source of interference to satellite communications. In 1999, the TRANSMITTER LOCATION SYSTEMS, LLC subsidiary was formed as a dedicated business unit to focus on the global availability and support of the TLS technology.

The development of TLS geolocation technology is a unique success story in the satellite communications industry. Since 1990, the company and its customers have successfully resolved over 12000 incidents of satellite interference. In a few cases, incidents of interference required a more comprehensive solution, an airborne surveillance technique called FINAL SEARCH , developed in 1996. The combination of TLS experts, the TLS NexGen and FINAL SEARCH have become the reliable and proven solution to satellite interference problems. The combination of these two technologies has a 100% record of success in locating interfering signals.

As TLS enters its third decade, we continue our commitment to technological and practical improvements in communications satellite interference geolocation. The need for suitable adjacent satellites for geolocation and the growing likelihood that the downlink footprints of interfered and adjacent satellites do not coincide led to the development of distributed mode TLS, a prominent and unique feature of the state-of-the-art TLS NexGen geolocation system. More recently, the uncertain present and future availability of satellite orbital elements has stimulated our development of Single Satellite Ephemeris Solution (SSES) geolocation solver software which requires the orbital elements of only one of the two satellites rather than both.

Today, nearly all major commercial satellite operators have installed TLS geolocation systems as an important component of their in-house command and control operations. Those TLS geolocation installations are supported by on-going customer support contracts with TRANSMITTER LOCATION SYSTEMS, LLC, enabling the satellite owners to work closely with the experts at the TLS Global Operations Center in Chantilly, Virginia.

The worldwide problem of satellite interference is further being addressed by TLS with the establishment of its TLS Global Network of processing stations with installations in China, France, Italy, Hawaii, Mexico and South America. When linked to the TLS Global Operations Center in the United States this one-of-a-kind network provides the communications satellite industry with the ultimate defense against satellite interference, both unauthorized transponder use and intentional disruption of transmissions.
