What Makes the Discount Garmin Nuvi 760 so Exact?
New technologies are introduced into the market every day, and some of the most advanced items available today are Global Positioning System (GPS) receivers. The GPS helps people locate their precise positions on the globe, find other points of interest, and get directions between locations. Many manufacturers have begun building and offering receivers, but one of the clear standouts is the discount Garmin nuvi 760 GPS receiver.
The GPS consists of satellites and receivers. The 24 satellites send signals to the receivers on the ground, which calculate their own locations (with an average accuracy of within 15 meters). To plot a two-dimensional location (latitude and longitude), the receiver needs to be able to read signals from three satellites. With the information from four or more satellites, a three-dimensional location can be determined.
The 24 satellites that make up the GPS were originally placed into orbit by the United States government to provide information supporting military operations around the globe. The government opened the system to civilian use (without cost) in the 1980s. Today companies sell a wide variety of GPS receivers that provide navigation. Many models, such as the discount Garmin nuvi 760 GPS, perform many other functions as well.
The 24 GPS satellites in the system orbit the earth at a rate of two times per day. Each satellite has a specific path that is designed to enable the entire system to blanket the earth with signal information. While the satellites travel along their paths, they send signals to receivers around the globe. The signals are only able to travel in a line of sight manner: they pass right through glass and clouds but are stopped by solids such as tall buildings and rock formations.
The signals sent by the satellites are constantly being read by the receivers on the ground. The receivers compare the precise time they receive each satellite's signal to the time the signal left the satellite. This tells the receiver how far it is from the satellite. Using this information and the signals from other satellites, the receiver is able to determine its precise position on the globe.
Once the group of satellites and the receiver have calculated the receiver's precise location, they can also determine other things helpful to the user. These include the user's distance from their destination, time to destination, speed, and bearing. The discount Garmin nuvi 760 GPS is one receiver that can perform not only these functions, but others as well.
For 24 hours each day, the GPS satellites transmit their signals to the earth, regardless of the weather conditions. They are powered by solar panels and have battery packs for backup power when needed. As they travel in their orbit of approximately 12,000 miles above the earth, small rocket boosters attached to the satellites keep them on course.
Although the satellites function virtually all of the time, there are situations in which it is more difficult to read the signal or calculate position. In some of these situations?such as when a signal bounces off of buildings or rock formations the signal's travel time is affected. Another difficult situation is when the GPS receiver's clock does not show the same time as the satellite's atomic clocks. Both of these situations affect the accuracy of the location calculations.
The discount Garmin nuvi 760 GPS unit includes twelve channels that can read multiple satellite signals at the same time. This makes the unit highly accurate in pinpointing the user's location. The twelve channels also make it more likely that the receiver can retain signals in difficult environments like forests or cities with tall buildings.
The popularity of GPS technology is sure to continue, and will probably even grow in the next few years. GPS units continue to be enhanced by their manufacturers, with even more features, functions, and benefits for their users. The future is certain to bring even more advanced GPS technology. - 21392
