CSS-905A Airborne Transmitter

CSS-905A can be factory set or user configured over a range of operating parameters, including radio frequency (RF) output power, frequency selection, input data rates, and Advanced Range Telemetry (ARTM) Tier 0, I and II modulation. Its flight history reduces selection and system design risks and provides opportunities for qualification-by-similarity (QBS) analysis. CSS-905A is a proven, high-reliability telemetry transmitter that has supported a full range of qualification testing by the most demanding programs.
