IRIG FQPSK-B STANDARDIZATION PROGRESS REPORTThis paper will provide an overview of the process used to develop the bandwidth efficient modulation sections of the Inter-Range Instrumentation Group (IRIG) standard. The modulation method selected was Feher’s patented quadrature phase shift keying (FQPSK-B). The important characteristics of a bandwidth efficient modulation method for aeronautical telemetry will be presented first followed by a summary of the results of the research, laboratory test, and flight test efforts. Future plans will then be summarized followed by the FQPSK-B sections of the current IRIG Telemetry Standard (the standard is available online at: http://tecnet0.jcte.jcs.mil/RCC/oldoc.htm).
