Abstract
A system () and method () of personal inertial navigation measurements can include measuring () an angle, measuring () an angular velocity independent of an angle measurement, measuring () an angular acceleration independent of the angle measurement and independent of an angular velocity measurement, and combining () 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 () noise caused by the angle measurement by using a sample and hold circuit () controlled by a higher ordered component to suppress noise from a lower ordered component.
