Gyroscopes are the key part of any inertial navigation system. They were invented more than a century ago and are used as a reference point to understand the inertial point of a moving body. From small ships to advanced spacecraft, quality gyroscopes have proven to play a major factor in the performance of a mission. In many cases, the gyroscope has been a ‘make or break’ device. As gyroscopes have evolved, so too have their applications. They have a vast and diverse array of applications, ranging from monitoring the orientation of an aircraft, or guiding an unmanned aircraft during flight, to stabilizing the frames of a camera. Other areas where gyroscopes are used include ballistic missiles, guiding the process of building runnels, fire control systems, satellite navigation, and more.
