Inertial navigation unit of French IRBM S3 IMUs work, in part, by detecting changes in pitch, roll, and yaw. An inertial measurement unit works by detecting linear acceleration using one or more accelerometers and rotational rate using one or more gyroscopes. [3] Some also include a magnetometer which is commonly used as a heading reference.

An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the ...
An inertial reference unit (IRU) is a type of inertial sensor which uses gyroscopes (electromechanical, ring laser gyro or MEMS) and accelerometers (electromechanical or MEMS) to determine a moving aircraft’s or spacecraft’s change in rotational attitude (angular orientation relative to some reference frame) and translational position (typically latitude, longitude and altitude) over a ...

The first railway in British North America, the Champlain and St. Lawrence Railroad, was built in the mid-1830s to 4 ft 8 + 1 ⁄ 2 in (1,435 mm) track gauge.This was followed by the Albion Colliery tramway in 4 ft 8 + 1 ⁄ 2 in (1,435 mm) and the Montreal and Lachine Railroad in 4 ft 9 in (1,448 mm).
