GPS In A Nutshell
Over twenty years ago, the United States developed a system of satellites circling the globe in order to help its military navigate the globe with accuracy. With multiple satellites in geo-synchronous orbit, units on land and sea can quickly get an accurate location and also a glimpse at the surrounding terrain.
The satellites send a signal to the GPS receivers on the surface of the Earth and then from there, the location is pinpointed. The system was then commercialized in the 1990s and it has literally taken off.
The most used GPS system is the Car GPS device. This is a fantastic device that will calculate the route from wherever your present position is, to the desired end point. All you will need to know is the address, or place name if it is a stadium or other point of interest. After this information is loaded into the device, it will perform course calculations and graphically display directions to your destination. If you need to deviate from the planned course, for a rest stop or restaurant, the GPS device will quickly recalculate the new coordinates and map out a revised route. Another nice option on some of the newer models is the ability to hear voice commands. The voice feature allows drivers to remain focused on the road in order to minimize accidents.
Since the technology has been available for decades, manufacturers and researchers have developed ways to make the GPS receiver smaller and smaller. They are now small enough to be placed into clothing and other small, inconspicuous items.
Because GPS has become smaller and the receivers and satellites are in constant contact, GPS tracking services have sprung up in recent years. These services give parents peace of mind by allowing them to know where their child is at all times. All the parent needs to do is place the GPS on the child and then monitor their child’s whereabouts on the service’s website.
Cheap GPS units mean only one thing – the adoption of their use by a large swath of the population. These inexpensive units mean that pretty much every car on the road has them on the dashboard so that the driver doesn’t get lost or waste money on gasoline spent going the wrong way.
For car GPS, you can go one of two ways when buying a new car. If it is an option to get the GPS system built in this is most desirable. The other option is to buy a car GPS unit and place it on your dashboard and reove it each time you leave your car. Either way you go, you will be happy you added GPS to your life.
