Abstract : In this paper, a detailed investigation of the random vibration test is presented for strapdown inertial navigation systems
(INS). The effect of the random vibration test has been studied from the point of view of navigation performance. The role of
distribution functions and RMS value is represented to determine a feasible method to reject or reduce vibration related error
in position and velocity estimation in inertial navigation. According to a survey conducted by the authors, this is the first time
that the effect of the distribution function in vibration related error has been investigated in random vibration testing of INS.
Recorded data of navigation grade INS is used in offline static navigation to examine the effect of different characteristics of
random vibration tests on navigation error.
