George-
<Any device that measures acceleration due to gravity
will find it inextricably confused with the other transient accelerations
that rough weather creates.>
I confess to having no experience designing inertial navigation systems, for aircraft, submarines, or flying cars. (They did promise us flying cars!<G>)
I don't see why a device measuring acceleration due to gravity could not be used to filter out--and thus remove--the effects of rough weather. It would seem that if the "sea state gravity" effects can be registered on the accelerometer chips, they can be subtracted from the overall effects in the fluxgate sensors, producing a net fluxgate reading without the rough weather effects.
What am I not seeing here?
