This study examines the effects of airframe vibration on the accuracy of a strapdown inertial navigation system. A stochastic model of the system error equations is included, as are two models of airframe vibration. software subroutines for model implementation in SOFE are included. A representative C- 130A flight profile was developed using a flight trajectory generator, PROFGEN. The system errors induced in the inertial navigation by simulating this mission are included as are those caused by vibration. Vibration induced errors were found to be very small and orders of magnitudes smaller than those caused by other error sources.
