With the help of a couple of satellites going around the earth we can find our position on the earth with very high accuracy by measuring ranges from these satellites. The satellite based navigation system is called the GPS (global positioning system). In the first part1 we described the basic principle of the operation of GPS. This part is about the mechanism and uses of GPS. 相似文献

Since ancient times navigators have been taking the help of celestial objects to find angles between the horizontal and the lines of sight to the celestial objects, in order to determine their position on the earth. Now, they would take the help of couple of manmade objects whizzing around the earth to find their position with very high accuracy, by measuring ranges from these objects. These objects are satellites and this article gives a brief introduction to a satellite based navigation system, called the GPS (Global Positioning System) in two parts. The first part introduces the basic principle of operation of GPS. 相似文献
