Abstract
Various implementations directed to correction of rotation rate measurements are provided. In one implementation, a method may include receiving rotation rate measurements about a first axis and a second axis from first gyroscopic sensors. The method may include receiving a first rotation rate measurement about a third axis from a second gyroscopic sensor. The method may include determining an estimated rotation rate measurement about the third axis based on the rotation rate measurements about the first axis and the second axis. The method may include determining a bias value based on a difference between the first rotation rate measurement about the third axis and the estimated rotation rate measurement. The method may include receiving second rotation rate measurements about the third axis from the second gyroscopic sensor. The method may include correcting the second rotation rate measurements about the third axis based on the determined bias value.
