Accelerometers are used alongside gyroscopes in inertial navigation systems. Inertial tracking use data from accelerometers and gyroscopes. The IMU contained hemispherical resonator gyroscopes and accelerometers. These devices included accelerometers, gyroscopes, and environmental and chemical sensors. This is accomplished by combining readings from accelerometers and gyroscopes mounted in the device. Each unit contains three solid-state gyroscopes and three accelerometers. Each MIMU is a combination of three accelerometers and three ring-laser gyroscopes. The system would be a north seeking stable platform controlled by gyroscopes and accelerometers. Automotive yaw sensors can be built around vibrating structure gyroscopes. His father was a gyroscope test technician, who specialized in gyroscopes. The sustainer also steered the rocket by thrusters guided by gyroscopes. This experiment measured the magnetic fields of four superconducting gyroscopes to determine their spin axes. This was used to update three axis gyroscopes which enabled spacecraft operations. Vibrating structure gyroscopes are simpler and cheaper than conventional rotating gyroscopes of similar accuracy. When gyroscopes 'saturate', thrusters are used to cancel out the stored momentum.
