Operation was relatively simple: a pilot or flight engineer would enter the individual waypoints by their latitude and longitude points and then the pilot or engineer would enter the starting location in latitude and longitude. The system used spinning mass gyroscopes and proof-mass accelerometers to

Carousel IV consisted of an inertial measurement unit (IMU) as its position reference, a digital computer to compute the navigation solution, and a control panel mounted in an aircraft's cockpit. It was used for long over water and over the North Pole aircraft navigation. Many aircraft were equipped
141:
The
Carousel IV system derives its name from the fact that the inertial reference platform was rotated 360° every 60 seconds as a technique to reduce drift and increase accuracy by countering systematic errors. Low drift operation was aided by maintaining the gyroscopes and accelerometers at a

constant temperature of 60 °C. The elevated temperature was maintained whenever the system was switched on in either the 'Standby', 'Align', 'Navigate' or 'Attitude' mode, as selected on the
Control Display Unit (CDU).
130:. Before the advent of sophisticated flight management systems, Carousel IV allowed pilots to automate navigation of an aircraft along a series of waypoints that they entered via a control console in the cockpit.
