Microsized Timing And Inertial Measurement Unit (T-IMU): Wafer (USA)
This is a Microsized Timing and Inertial Measurement Unit (T-IMU): Wafer. It was made by University of California, Irvine and MicroSystems Laboratory of the University of California, Irvine and collaborator: Defense Advanced Research Projects Agency (DARPA).
This microscale navigation system can measure position with high precision, even when GPS is unavailable. Developed to provide fully integrated positioning and navigation for aircraft and missiles, the T-IMU includes microscopic components, making it possible to embed new tools within portable devices. The T-IMU’s pyramidal shape was designed to provide structural integrity and to hold sensors to detect motion in different directions. Each face of the T-IMU holds a rotation-sensing gyroscope or linear motion-sensing accelerometer. An additional sensor keeps track of time. Time measurements provide references for the inertial sensors much like GPS, which utilizes precise atomic clocks on orbiting satellites and measures the arrival times of signals moving at the speed of light. The accuracy of the T-IMU’s time reference over short periods is on par with atomic clocks, but its stability decreases over longer periods, meaning it cannot completely replace GPS or atomic frequency standards.
