Study Notes
Navigation
Definition
- Navigation refers to the process of planning, recording, and controlling the movement of a person, vehicle, or object from one place to another.
Types of Navigation
- Pilotage: navigating by using visual references such as landmarks, beacons, and charts.
- Dead reckoning: navigating by tracking speed, direction, and time traveled from a known location.
- Celestial navigation: navigating using astronomical objects such as the sun, moon, and stars.
- Radio navigation: navigating using radio signals from beacons or satellites.
- GPS (Global Positioning System): navigating using a network of satellites orbiting the Earth.
Navigation Tools
- Maps: visual representations of an area, showing features such as roads, landmarks, and boundaries.
- Charts: specialized maps for navigation, often showing waterways, coastlines, and hazards.
- Compasses: instruments that indicate direction, using a magnetized needle that aligns with the Earth's magnetic field.
- GPS receivers: devices that receive GPS satellite signals, providing location and direction information.
- ** Sextants**: instruments used to measure the angle between the sun, moon, or stars and the horizon, for celestial navigation.
Navigation Skills
- Route planning: determining the most efficient and safe route between two points.
- Waypoint navigation: using GPS or other means to navigate to a specific point or series of points.
- Course correction: adjusting direction to stay on course, taking into account factors such as wind, currents, or other external influences.
- Position fixing: determining one's current location, using various navigation tools and techniques.
