Modular, multiband software-defined radio
L3Harris’ C/TT-600 is a modular, multiband software-defined radio with a flexible parts program designed to support a wide range of applications and orbits including LEO, MEO, GEO, Cislunar and deep space. Designed with the user in mind, C/TT-600’s “sliced” architecture approach enables selection of a variety of configurations which can be purchased off-the-shelf or customized for unique mission requirements.
C/TT-600 is the culmination of over 60 years of design experience providing UHF-, S-, X- and Ka-band high reliability, mission-critical communications equipment for spacecraft applications spanning LEO to deep space. C/TT-600 is derived from high-TRL radio designs with spaceflight heritage and is specifically tailored to meet the demands of the Artemis generation.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
