Inertial Measurement Units provide inertial attitude and velocity data to a spacecraft's guidance, navigation, and control system. On the space shuttle, IMU data are used to convert steering commands into control surface, engine gimbal, and...

An Inertial Measurement Unit, or IMU, is the main component of an inertial guidance system used in vehicles such as airplanes and submarines. An IMU works by sensing its own rate and direction of motion using a combination of accelerometers and...

By Randy Frank, Contributing Editor Several programmable features add to unit's factory-calibrated precision Inertial measurement units (IMUs) for applications such as automobiles and handheld positioning systems have grown rapidly in recent years. However, lower volume industrial applications have different requirements. Instead...

A solid-state GPS navigation system enables widespread use of GPS in smaller manned and unmanned aircraft, achieving the accuracy and robustness typically associated with larger, higher cost systems. The NAV420's sensors, data-acquisition elements, and Kalman-filter-based algorithm allow smaller aircraft to be deployed more...
