Full Form of GPS | GPS Full Form | What is GPS | About GPS
Full Form of GPS is Global Positioning System: (GPS) Global Positioning System. It’s a satellite-based navigation system that permits ground users to see their actual location, velocity, and time twenty-four hours daily, altogether atmospheric condition, everywhere the globe. It’s maintained and developed by the U.S. Department of Defense and was essentially designed to help soldiers and military vehicles however when some decades it created accessible to anyone having a GPS receiver. It’s widely used to track vehicles and follow the most effective route from one place to a different place by Airlines, shipping companies, traveller corporations, drivers etc.
Full Form of GPS: The first GPS was developed within the 1960s to help the ships of us Navy in navigating the oceans additional accurately. The primary system started with 5 satellites that enabled ships to examine their location once each hour. There are twenty-four satellites and some spare satellites in orbit with an amount of twelve hours (two orbits per day) at a height of regarding 11,500 miles. Satellites are placed such that four satellites are higher than the horizon, from any point on Earth. In order to receive the data GPS device can 1st establish a reference to three to four satellites. GPS satellite broadcasts a message together with the location of the receiver. GPS receiver combines the message from totally different satellites to calculate the precise position exploitation the method known as triangulation.
GPS satellites need an unobstructed line of sight for the communication. Hence, this technology isn’t ideal for the indoor use. There some devices use nearby cell towers and public Wi-Fi signals. This technology is named LPS (Local Positioning System) and could be a substitute of GPS.
According to Wikipedia:
The Global Positioning System (GPS), originally Navstar GPS, is a space-based radio navigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
The GPS system does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information. The GPS system provides critical positioning capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver.
The GPS project was launched by the U.S. Department of Defense in 1973 for use by the United States military and became fully operational in 1995. It was allowed for civilian use in the 1980s. Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS and implement the next generation of GPS Block IIIA satellites and Next Generation Operational Control System (OCX). Announcements from Vice President Al Gore and the White House in 1998 initiated these changes. In 2000, the U.S. Congress authorized the modernization effort, GPS III.
