As a leader in the industry, Thales Communications provides its expertise for the development of products that exploit SDR technology. One example is the U.S. Air Force's Combat Survivor Evader Locator (CSEL) system. CSEL replaces line-of-sight radios with multimode satellite radios that allow for immediate communication with downed pilots (FLTSATCOM, SARSAT, AM Ground-to-Air).

Thales is a supplier to prime contractor Boeing, providing design and production of the VHF/UHF transceiver module used in the system. Thales' VHF/UHF transceiver module provides the CSEL radio with its communications capabilities by combining a powerful software-defined architecture and a multi-mode satellite radio on one board slightly larger than a credit card.
