    Accelerometer Noise PSD to Velocity Random Walk

    That was the initial way I went about looking at this once the units made sense to me. But, I happen to know this spec was written such that the QA3000 passes, so that drove me to keep researching. I came across an IEEE standard (IEEE 952-1997, annex C.1.1, "angle random walk" -- it was...

    Accelerometer Noise PSD to Velocity Random Walk

    My question has changed due to more research. Here it is: I have a specification that says this: "The velocity random walk due to the white noise portion of the acceleration self-generated output noise PSD shall be less than 15 (micro-m/s)/sqrt(s)." I have the PSD for my accelerometer, in...

    Accelerometer Noise PSD to Velocity Random Walk

    I have the intrinsic noise PSD spec for Honeywell's QA3000 accels, and I need to find the velocity random walk due to noise to show that I'm within my allowable. The PSD is given in units of g^2/Hz vs Hz. I'm given a velocity random walk due to noise spec of 15 (micro-m/s)/rt(s) that I must be...
