Unlock the Power of True Bearing for Precision Navigation and Enhanced Safety
True Bearing (TB), a fundamental concept in navigation, refers to the angle measured clockwise from True North to the direction of an object or destination. It provides a precise reference for accurate navigation and is essential for ensuring safety and efficiency in various applications, including maritime navigation, aviation, surveying, and more.
Understanding True Bearing
| Term | Definition |
|---|---|
| True North | The direction towards the Earth's geographic North Pole |
| Magnetic North | The direction towards which a compass points, influenced by the Earth's magnetic field |
| Variation | The angle between True North and Magnetic North, varying with location |
| Navigation Method | Reference Point |
|---|---|
| True Bearing | True North |
| Magnetic Bearing | Magnetic North |
| Compass Bearing | Compass Needle |
Determining True Bearing
To determine True Bearing, several methods can be employed:
