20080294342 | Position Detecting Device And Position Detecting Method - A dead reckoning unit calculates vehicle position from a pitch angle and a yaw angle of dead reckoning sensors, a sensor installation pitch angle and a sensor installation yaw angle, and a moving distance calculated by a speed sensor, and calculates vehicle speed from an acceleration signal.

20090171585 | Computational scheme for MEMS inertial navigation systemes - A computational scheme for an INS which utilizes micro-electro mechanical systems (MEMS) sensors is disclosed resolving issues of unnecessarily large computational burden and numerical instability which happen in using conventional methods using high-end inertial sensors. The first aspect to reduce computational burden in MEMS application is to omit computing Earth radii of curvatures that were used in a high-frequency application. The second aspect is to ignore the Earth rotation and the rotation of the local tangent plane with respect to Earth in the computation which are much smaller than noise and bias in the MEMS sensor output. The last aspect is to assume that the absolute amount of the platform pitch and roll angles is less than 90 degrees. This assumption results in only four parameters required to track in the direction cosine matrix describing the transformation from the local tangent plane to the platform where all the nine elements are tacked in the conventional method. According to the aspects noted above, the computational load will be one-fourth of the conventional method without degradation of accuracy. | 07-02-2009 |
