  • Navigation Instruments

The drift rate in a single-degree-of-freedom gyro resulting from coherent oscillatory rates about the spin reference axis (SRA) and input reference axis (IRA).


It occurs only when gyro and loop dynamics allow the gimbal to move away from null in response to the rate about the input reference axis, resulting in a cross coupling of the spin reference axis rate. This drift rate is a function of the input rate amplitudes and the phase angle between them.
