Navigation systems have definitely taken off as a staple from being the mainstays of airplanes and large ships. Nowadays, global positioning navigation units can fit in the palm of your hand thanks to a small GPS device, or even in your car. With the many roads that go around the cities and all the addresses that need to be remembered, a portable navigation device can be quite a boon to commuters, whether you drive or take public transportation.
The global positioning system works fairly simply. A small device or a beacon would home in on the satellites revolving in orbit around the Earth. It sends out signals that could then be reflected by at least two other satellites to come up with the exact coordinates of an object on the Earth's surface. Depending on the quality of the device, the accuracy and the precision of the coordinates can be greatly increased, and is often accurate up to a few feet.
The most obvious application of navigation systems is in the autopilot requirements of aircraft. For almost two decades now, airplanes have been running on autopilot systems that allow the pilot to relegate the actual flight controls to the airplane’s computer, and then the pilot can just oversee how the plane cruises while at altitude. The pilot is still the one responsible for the take-off duties, until the proper cruising altitude is achieved. Landing is also the pilot’s duty, although oftentimes, landings are already guided by computers, to ensure safety. During times of turbulence, the pilot can also take over from the autopilot to fine tune the necessary steering to evade clouds and moisture that may cause undue shaking in the fuselage.
Ships likewise use this type of navigation system to steer clear of reefs and other moving objects in the open seas. The navigation systems are in complement to other devices that ships use to track other objects at sea, such as radar and visual inspection.
Car navigation systems sure have made traveling on land a lot easier. From being a global positioning system beacon, a device can easily be mounted on a car’s dashboard to help you navigate through the maze of city avenues, residential streets and highways. To make the device a lot safer to use, most navigational systems fitted into cars are also designed to cue the driver through voice prompts, so that the driver’s attention can remain on the road. The navigation software on these devices are often updated to add new landmarks.
Satellite navigation has definitely changed the game as far as driving and traveling goes. Without having to even read a map, it is now much easier to know how to find even obscure locations. You can even use revolutionary navigation systems that fit in the palm of your hand. With constant updating of landmarks, establishments and street details on the Internet, you get up to date mapping information at low costs (or even free). It’s great how technology can marry portable navigation with convenience.
