20130173207 | Miniaturized Inertial Measurement Unit and Associated Methods - An inertial measurement unit includes a base having a plurality of physically distinct sectors, upon which are positioned thereon groups of orthogonally oriented angle rate sensors, each group positioned on a different sector of the base. High-G and Low-G orthogonally oriented accelerometers are also positioned on the base. A processor is positioned on the base having software resident thereon for receiving signals from the angle rate sensors and the accelerometers. Software is also resident on the processor for calculating from the received signals one or more of the following: a change in attitude, a change in position, a change in angular rate, a change in velocity, and a change in acceleration of the unit over a plurality of finite time increments. | 07-04-2013 |

Three high-G orthogonally oriented accelerometers are also positioned on the base, as well as three low-G orthogonally oriented accelerometers. A processor is positioned on the base having software resident thereon for receiving signals from the three groups of angle rate sensors and the three high-G and three low-G accelerometers. Software is also resident on the processor for calculating from the received signals one or more of the following: a change in attitude, a change in position, a change in angular rate, a change in velocity, and a change in acceleration of the unit over a plurality of finite time increments. Preferably, each gyro is subjected to oversampling, temperature and bias compensation, and bias offset compensation. | 12-31-2009 |
