A navigation technique is
a way to determine the navigator’s position and to set the desired course
. There are different methods of locating your position, different plotting methods, and also different ways to determine your course. The system of locating, plotting, and setting a course is called a navigation method.
The methods used in this chapter include
pilotage—navigating by reference to visible landmarks
, dead reckoning—computations of direction and distance from a known position, and radio navigation—by use of radio aids. Figure 16-1. Sectional chart and legend.
Navigation technology is
about the ability to mainly store, or present information and recall the locations of objects in places or spaces
and often within a context of time. It is about the tools and technique of getting from place to place.
- Main Navigation.
- Local Navigation.
- Contextual Navigation.
1 :
the act or practice of navigating
. 2 : the science of getting ships, aircraft, or spacecraft from place to place especially : the method of determining position, course, and distance traveled. 3 : ship traffic or commerce.
Three main types of navigation are
celestial, GPS, and map and compass
. In order to better understand why we teach map and compass at High Trails, it is helpful to learn the basics of all three techniques.
A satellite navigation device, colloquially called
a GPS receiver
, or simply a GPS, is a device that is capable of receiving information from GNSS satellites and then calculate the device’s geographical position.
Pilotage or Piloting
is the most common method of air navigation. This method, the pilot keeps on course by following a series of landmarks on the ground. Usually before take-off, pilot will making pre-flight planning , the pilot will draws a line on the aeronautical map to indicate the desired course.
One of the most familiar navigational tools in the world is
the Compass
. The compass can be used as a navigational tool on land, at sea, and in the air.
VORs
work on the principle of the phase difference in two radio signals
. … That’s how a VOR works. A rotating directional signal is broadcast from the VOR, while a second (omnidirectional) signal is broadcast only when the rotating signal passes north.
Web navigation refers to
the process of navigating a network of information resources in the World Wide Web
, which is organized as hypertext or hypermedia. The user interface that is used to do so is called a web browser. … Hierarchical navigation systems are vital as well since it is the primary navigation system.
A keyboard key used to move the pointer (cursor) around on the screen. They include the
four Arrow keys, PageUp, PageDown, Home and End keys
.
A navigation menu is
a list of a links pointing to important areas of a website
. They are usually presented as a horizontal bar of links at the top of every page on a website. Navigation menus give your site structure and help visitors find what they’re looking for.
Explanation:
Compasses
, which indicate direction relative to the Earth’s magnetic poles, are used in navigation on land, at sea, and in the air. Compasses were being used for navigation by the 1100s, and are still the most familiar navigational tools in the world.
An automotive navigation system is
part of the automobile controls or a third party add-on used to find direction in an automobile
. It typically uses a satellite navigation device to get its position data which is then correlated to a position on a road. When directions are needed routing can be calculated.
navigation. Fixing a vessel’s position by
taking two compass bearings
. Taking compass bearings to known points—in this case, the headland (bearing 045°) and the buoy (bearing 120°)—enables the navigator to “fix” the vessel’s current position at the intersection of the two bearings.
