1. Cardinal Directions (North, South, East, West):
* Compass: A compass uses the Earth's magnetic field to point towards magnetic north, which is close enough to true north for most purposes.
2. Azimuth (Degrees from North):
* Compass with a degree scale: Many compasses have a circular scale that shows degrees from 0° to 360°.
* GPS: Global Positioning System receivers provide a precise azimuth (bearing) to your destination.
* Surveyor's Theodolite: This instrument is used in surveying to measure angles with high accuracy.
3. Latitude and Longitude (Geographic Coordinates):
* GPS: Global Positioning Systems are the primary means for determining latitude and longitude.
* Celestial Navigation: Historically, sailors used celestial bodies (stars, sun, moon) to determine their position, and thus their latitude and longitude.
4. Direction of Motion:
* Gyroscope: A gyroscope is used to measure and maintain orientation.
* Accelerometer: An accelerometer measures acceleration, which can be used to determine the direction of movement.
Important Note: While many tools can measure direction, the accuracy and precision of the measurements vary depending on the instrument and its intended use.
