Increasingly, modern aircraft use sophisticated gyros (laser ring gyros) to detect even minute changes in accelerations in all 3 aircraft axes. From this the attitude of the aircraft can be calculated and displayed on EFIS systems and through a series of integrators the velocity and position of the aircraft can be determined. This is the IRS the inertial reference system. I hope some of this is right!
