Over 40 year history of producing space qualified hardware

L-3 Communications, Telemetry and RF Products (T&RF) offers a wide range of space-qualified products available for commercial, civil, Government and military satellite communications. L-3 T&RF is the primary supplier of Telemetry, Tracking and Command (TT&C) Transponders offering state of the art technology and flexibility for short and long term commercial and military applications. They are backed by a strong flight heritage and feature high reliability and radiation hardening to satisfy virtually any environment. Our next generation TT&C Transponder (CXS-2000) offers additional flexibility and can be configured with up/down converters to operate at frequencies up to K-band. L-3 T&RF has been selected on AEHF, MUOS and multiple classified programs.

Our flight-proven high data rate X-Band Transmitters offer flexibility in modulation format (BPSK, SQPSK, 8PSK), output power (standard 3 or 6 watts) and interfaces and are extremely well suited for satellite payload transmission.

L-3 T&RF also offers a complete range of embedded and stand-alone COMSEC products that can be customized for your specific application. These units are modular and offered with various NSA approved devices depending upon your program requirements. We offer an extensive background in generation and approval of NSA required documentation which is critical in obtaining program approval.

Finally, L-3 T&RF offers a multitude of ground telemetry processing equipment including high power amplifier and mission control software for satellite command and control. L-3 Ground products compliment our Space qualified hardware, creating the only complete, spaceborne and ground systems capability from a single supplier in the industry.
