Drift Meter

A Drift Meter is a navigational instrument used to measure the drift angle and speed of a vessel or aircraft. It is typically used in marine and aviation applications to determine the effect of wind or current on the movement of the vehicle.

The Drift Meter consists of a compass or gyrocompass, a wind vane, and a speedometer. The compass or gyrocompass provides the heading of the vehicle, while the wind vane measures the direction and strength of the wind. The speedometer measures the speed of the vehicle through the water or air.

By combining the information from these instruments, the Drift Meter can calculate the drift angle and speed. This information is important for navigation purposes, as it allows the pilot or navigator to make adjustments to the course and speed of the vehicle to compensate for the effects of wind or current.

In summary, a Drift Meter is a navigational instrument used to measure the drift angle and speed of a vehicle, such as a vessel or aircraft, in order to account for the effects of wind or current during navigation.
