TSi develops custom signal processing software for such diverse systems as satellite ground support operations, prognostic monitoring of systems and equipment, and custom sensor development.

Signal processing is one of the cornerstone capabilities of TSi. Most of the location processing algorithms used in current SARSAT ground station equipment were developed by TSi personnel in early contracts with NASA in the late 1970s. Subsequently in 1989, TSi entered the SARSAT ground station market and is now the world's leading supplier of satellite-aided search and rescue technology for the international COSPAS-SARSAT system.

TSi has state of the art computing equipment to perform highly intensive numerical computations. TSi also has several solutions for high speed data acquisition.
