Inertial Navigation Systems have to take the Coriolis effect and earth rotation into account to be able to correctly calculate the movement and orientation of the aircraft over the globe without any reference to the outside because the accelerometers are affected by the Coriolis effect. There are explicit control loops in the electronics and navigation equations in the software to account for Coriolis.
"Inertial Navigation (IN) is the type of navigation that uses accelerometers and a computer to calculate via dead reckoning one’s position. IN is fundamentally achieved by the double integration of acceleration and correcting for gravitational fields in the computations along with other considerations such as coriolis acceleration. Currently IN is used for navigation in astronautics, aeronautics, marine and land, but the technology goes beyond navigation"
See page 23, Navigation Equations
"The navigation computer uses these equations to compute the vehicle’s position taking measurements form the sensors, correcting them to account gravity, coriolis, and the earth’s rotation, and then computing the vehicles movements."
"A moving vehicle experiences forces like Coriolis and centripetal which related to the vehicle’s craft rate. These forces need to be accounted for to accurately navigate." page 65
