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-term, as well as long-term applications.

The CXS-610 builds upon our strong flight heritage from the very similar CXS-810 (SGLS) transponder. It continues the tradition of meeting high-reliability and radiation hardening mission requirements with over 300,000-hours of successful on-orbit operation since 2007.

The CXS-610 is the high-reliability choice for a STDN-compatible transponder. It provides TT&C between STDN and DSN ground systems and NASA or ESA satellites, and can also be used for commercial TT&C applications.

The CXS-610 is a Technology Readiness Level 9 (TRL-9) design, currently in-orbit on several successful NASA programs. Similar STDN transponders, (CXS-600B), have also successfully flown on many NASA and commercial satellites, including the Lunar Prospector mission. The mission ended in 1999.

The CXS-610 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 and integrated diplexer capabilities.
