At least seven ways to measure the heading of a vehicle have been described. [1] Heading is typically based on cardinal directions , so 0° (or 360°) indicates a direction toward true north , 90° true east , 180° true south , and 270° true west .
In nautical navigation the relative bearing of an object is the clockwise angle from the heading of the vessel to a straight line drawn from the observation station on the vessel to the object. The relative bearing is measured with a pelorus or other optical and electronic aids to navigation such as a periscope, sonar system, and radar systems ...
Air traffic controls can only infer the aircraft heading from the ground track of an aircraft, which may not reflect the aircraft's actual heading due to drift angle caused by the wind. As a result, pilots should give due consideration and apply drift correction when an air traffic controller provides traffic advisories.
Solve for true heading and ground speed. This type of problem arises during flight planning or during a flight, when there is a need to determine a true heading to fly and a ground speed with which to compute an estimated time of arrival. The traditional method of solving wind triangle equations is graphical.
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.

These instruments are used primarily to measure the elevation or altitude of a celestial object: Back staff, the best known of which is the Davis' quadrant. It could measure the altitude of the Sun without having the navigator directly observe the Sun. Cross staff, an older instrument long out of use.
