Abstract : Development of micrometeorite detection systems to be employed on specific satellite vehicles is discussed. Historical background is presented on micrometeorite phenomena and the general theory of the acoustic technique for micrometeorite detection. Development of the detection system was the result of combining a suitable sensor assembly an ultrasensitive amplifier and a digital to analog computer, to bether with a compatible DC to DC power converter. An engineering revision in the amplifier, discriminator and DC to DC power converter was later proposed and authorized. Subsequent developments in production requirements and modifications which led to Model D14DNO1A-B-C are presented. The calibration technique employed for the early micrometeorite detection system is compared to a unique ''Electronic Striker'' which was used for calibration on later odels. Data from three micrometeorite detection systems, which were flown on the satellite 1961 alpha 1, were evaluated.
