Generic filters

L3 Telemetry & RF Products (L3 T&RF) is a primary domestic supplier of Telemetry, Tracking and Command (TT&C) transponders offering proven designs and flexibility for short- and long-term applications.

The CXS-810/C SGLS transponder continues the tradition of meeting high-reliability and radiation-hardening mission requirements with more than 70 delivered transponders and over 1.5 million hours of successful on-orbit operations since 1997.

The CXS-810/C meets the high-reliability U.S. Department of Defense (DoD) standard for a SGLS-compatible transponder, providing TT&C between U.S. Air Force satellite control facilities and military satellites. The CXS-810/C is provided either with embedded encryption and decryption, or is compatible with external encryption devices, such as L-3 T&RF’s MCU-110B.

The CXS-810/C is a Technology Readiness Level 9 (TRL-9) design currently in orbit on many successful programs. The CXS-810/C utilizes a custom radiation-hardened, multi-function ASIC which results in reduced mass, power consumption, footprint and improved performance. Ranging, coherency, convolutional encoding, code conversion, direct modulation and subcarrier modulation are all standard features.

Optional configurations include custom interface characteristics for command function inputs, telemetry outputs, dual encryption, simultaneous dual modulation and integrated diplexer capabilities.
