Research: MEMS IMU carouseling for ground vehicles

September 13, 2016By
Collin-Jussi

Micro-electromechanical system (MEMS) gyroscopes have advantages for orientation sensing and navigation as they are small, low cost and consume little power. However, the significant noise at low frequencies produces large orientation errors as a function of time. Controlled physical rotation of the gyroscope can remove the constant part of the gyro errors and reduce low-frequency noise. As adding motors for... read more

HRL to develop inertial sensor tech for DARPA

April 12, 2016By

The Defense Advanced Research Projects Agency (DARPA) has awarded HRL Laboratories $4.3 million to develop vibration- and shock-tolerant inertial sensor technology that enables future system accuracy needs without utilizing GPS. While GPS provides sub-meter accuracy in optimal conditions, the signal is often lost or degraded due to natural interference or malicious jamming. HRL Laboratories, based in Malibu, California, is a corporate research-and-development... read more
