How to select the gps system that is right for you

The Global Positioning System is a U.S. space-based global navigation satellite system. It provides reliable positioning, navigation, and timing services to worldwide users on a continuous basis in all weather, day and night, anywhere on or near the Earth. It has been a fully operational phenomenon since April of 1995.

An enormously useful tool and tracking device, gps is used for map-making, surveying, commerce, scientific uses, surveillance and for recreational use in hobbies such as geo-caching and way-marking. Its precise time reference is also used in many scientific applications, including the study of earthquakes.

What is gps to the world of today and tomorrow?

As its uses have expanded, the question of what is gps has come to be defined in so any different ways. It has become a navigational mainstay of transportation systems all over the world. Disaster relief, satellite tracking, navigation for aviation, ground and maritime operations depend almost entirely on gps for location and timing-capabilities. The accurate timing provided by gps has seeped into the world of banking, mobile phones and even the control of power grids. GPS signals are instrumental in the accurate, efficient and economical performances of surveyors, farmers and geologists.

What is gps when used in a car?

A car gps system is one of the best gadgets you can install in your vehicle. Meant exclusively for navigational use while driving, most systems have a street- mapping feature, which offers directions to your intended destination. GPS units for automobiles usually cost between $200-$250. A gps system for a vehicle will typically feature a big display screen, which makes it easy to read without taking your eyes off the road for more than a few seconds. GPS devices do not run on their own stamina and rely entirely on the vehicleís supply of power.

What is gps made of?

GPS has three components. These include: between 24 and 32 satellites orbiting the Earth, four control and monitoring stations on Earth, and the GPS receivers owned by users. GPS satellites broadcast signals from space that are used by GPS receivers to provide three-dimensional location (latitude, longitude, and altitude) plus the time.

What is gps for you?

There is no such thing as the perfect GPS navigation system, as one size will never fit all. Everything is relative and depends entirely on what you need the GPS to do for you and how you plan to use it. Just think of that old adage about one manís (or womanís) meat and another manís (or womanís) poison and well, you know the rest. Learn how to make the right choice for your new navigation system and you canít go wrong.

Buying a gps is like buying any other gadget or appliance. The same rules apply. Shop around for the best buy in terms of what you need and be happy that the next time you go shopping a presence in your car will be telling you which way to go, making the location of foreign shopping malls so much easier to find!
