An Overview of Global Position System (GPS) and Its Technology of Navigation | Original Article

ABSTRACT:

GPS is one of the most fantastic utilities ever discovered by man. The Global Positioning System GPS is a satellite based Navigation System made up of at least 24 satellites that are eleven thousand nautical miles in space and in six different orbital parts. The satellites are constantly moving to complete orbits around the earth in just under24 hours. GPS works in any weather conditions anywhere in the world, 24 hours a day, with no subscription fees or setup charges. The US Department of Defense (USDOD) originally put the satellite into orbit for military use, but they were made available for civilian use in the 1980s. [www.ja-gps.com.au/what-isgps] by Johny.
