GPS stands for Global Positioning System and the System refers to a network of satellites that orbit the earth and transmit information back constantly. A handheld GPS receiver is a GPS navigator unit that is highly portable and can receive information from the satellites so as to pinpoint certain locations on the ground, in the air, or on the water.The 3 Parts of GPS GPS consists of three parts; space, control, and the user. Space refers to the satellites, control refers to the control stations on earth, and user is the person who operates the GPS.The SatellitesCurrently, there are 24 satellites orbiting the earth once every 12 hours. They were originally launched by the US Department of Defence for military purposes but they are now also used for civilian use. A GPS receiver needs to lock into at least three satellites to give a 2D location of longitude and latitude and four or more satellites to give a 3D location of longitude, latitude, and altitude.When the GPS receiver’s position has been determined, other measurements can be calculated like the speed the user is travelling, the trip distance

GPS or Global Positioning System is a satellite navigation system. More than 24 satellites broadcast timing signals that allows the GPS receiver to determine the latitude, longitude and altitude of an object. GPS Satellite Tracking can be used to navigate vehicles and ships in any weather at any time on any part of the planet.GPS Satellite Tracking is an indispensable tool that is used for map-making, land surveying and navigation. It provides a precise time reference that is vitally important for scientific research as well as telecommunications. These amazing devices can judge the position, speed and altitude with a high level of accuracy.GPS tracking was developed by United States Department of Defense and was officially named as NAVSTAR GPS, Navigational Signal Timing and Ranging Global Positioning System. The first experimental satellite of the GPS Satellite Tracking system was launched in 1978. In 2005, the next generations of GPS satellites were added to the satellite fleet. These satellites have an additional capability that includes L2C, the civilian GPS signal that increases reliability as well as accuracy.GPS Satellite Tracking Functioning:There are over 24 satellites in orbit approximately 12,600 miles

After going through this entire article, you will come to know what are GPS, how it works, recent improvements, its technology and the benefits. This is in regard with both the professionals and the public. First and the foremost is its expansion, GPS stands for Global Positioning system and it usually refers to the GPS receiver. Since 1980s, the American department of defense is using the GPS system for their operations. Later, they made it available for the public in reasonable rates. This receiver is capable of receiving signal from the satellites, circling the earth. There are totally 24 satellites, out of which minimum of three or four are visible from the earth. Everyday, they approximately make two circles around our earth.GPS receiver is capable of recognizing four or more satellite signals sent to the earth. Through these signal, the receiver calculates its distance to the satellite and finally locates its position on the earth. This is the principle behind the GPS system. It is enough if the receiver locates just three satellites but it will always try to locate as many as possible to generate more
