Career in NASA

Carreño is credited with inventing and developing the Single Frequency Multitransmitter Telemetry System in 1983. He also designed and conducted experiments for the real-time evaluation of the Viper single board computer while working in the instrumentation of the F-106 lightning research aircraft. Carreño continued his higher education by enrolling at the Old Dominian University, where in 1985 he obtained his Masters Degree in Electrical Engineering. In 1986 he was granted the patent for the SFMTS, U.S. Patent # 4,631,538.
