Part II Military Avionics System 0 Introduction Evolution of avionics Origination of avionics -- Avionics is a word coined in the late 1930s to provide a generic name for the increasingly diverse functions being provided by Aviation electronics. Avionics = Aviation + electronics -- to aid the pilot better performing the missions A brief chronology of military avionics 1910s: the first airborne radio experiments the first autopilot experiments 1930s: electronic aids: blind flying panels radio ranging non-directional beacons ground-based surveillance radar single-axis autopilot 1940s: VHF communications IFF (identification friend or foe) gyrocompass attitude and heading reference systems airborne intercept radar early electronic warfare systems military long–range precision radio navigation aids two-axis autopilot 1940s: VHF communications; IFF (identification friend or foe); gyrocompass; attitude and heading reference systems; airborne intercept radar; early electronic warfare systems; military long–range precision radio navigation aids; two-axis autopilot. 1950s: TACAN (tactical air navigation); airborne intercept radar with tracking capability and Doppler radar; medium pulse repetition frequency (PRF) airborne intercept radar ; mission computers ; inertial navigation systems. 1960s: integrated electronic warfare systems; fully automated weapon release; terrain-following radar ; head-up display; laser target marking technology; early digital mission computer. 1960s: integrated electronic warfare systems; fully automated weapon release; terrain-following radar ; head-up display; laser target marking technology; early digital mission computer. →to be concluded: Technology improvements drive the development of avionic systems Avio
