Answer 3

#### The Device That Determines the Direction of the Horizon The device that determines the direction of the horizon is called a **gyrocompass**. A gyrocompass is a navigational instrument that uses the Earth's rotation to determine true north. It is commonly used on ships and aircraft to provide accurate heading information. Unlike a magnetic compass, which relies on the Earth's magnetic field, a gyrocompass uses the principle of gyroscopic precession to maintain a stable reference to true north. It consists of a gyroscope that spins rapidly and is mounted on a set of gimbals, allowing it to remain level and aligned with the Earth's rotation. When the gyrocompass is aligned with the Earth's rotation, it can accurately determine the direction of the horizon. This information is crucial for navigation, as it allows sailors and pilots to maintain a steady course and avoid drifting off course. **Note:** Unfortunately, I couldn't find specific search snippets to cite for this information. However, the concept of a gyrocompass is well-established and widely known in the field of navigation.
