A motor inside the gyrocompass keeps the gyroscope spinning, so the gyrocompass will continue pointing toward north and will adjust itself swiftly and accurately even if the boat is in rough seas or the plane hits turbulence.
On returning to the starting point, the spin axis of the gyroscope (green arrow) would have turned 90 degrees from its original heading.
These guidance systems consist of a small spinning device called a gyroscope which keeps a constant axis orientation and thus helps to orient the missile.
Each gyroscope 's axis, while maintaining its direction with respect to local space-time, will no longer align on the far-off star.
A three-axis flight control system uses a heading reference unit and a vertical gyroscope to provide flight stability.
When the axis of a gyroscope is rotated the gyro attempts to make the plane of the rotation of the axis become the new plane of rotation for the gyro.
The earth can be thought of as a gigantic gyroscope , spinning at over 1000 miles per hour at its equator.
The prototype device is able to monitor its orientation using an embedded gyroscope .
According to the original scheme, spacewalking astronauts would have replaced failing batteries, gyroscopes and fine-guidance sensors.
However, in the days of vacuum tubes and mechanical gyroscopes , development could not move along fast enough to get this weapon into combat before the war ended.
