A system (400, 500) and method (800) of personal inertial navigation
measurements can include measuring (802) an angle, measuring (804) an
angular velocity independent of an angle measurement, measuring (806) an
angular acceleration independent of the angle measurement and independent
of an angular velocity measurement, and combining (808) the angle
measurement, the angular velocity measurement, and an angular
acceleration to provide an angled output. The angle measurement can be
measured using a compass or magnetic field, the angular velocity can be
measured using a gyroscope (such as a MEMS gyroscope), and the angular
acceleration measurement can be measured using an angular accelerometer
(such as a molecular electronic transfer device having a magneto
hydrodynamic effect device). The method can further include suppressing
(810) noise caused by the angle measurement by using a sample and hold
circuit (504) controlled by a higher ordered component to suppress noise
from a lower ordered component.
