What is GPS?
The term GPS means a global positioning System (GPS) which is a satellite navigation system consisting of about 24 satellites that accurately identify and localize the exact location of an individual or any object on Earth.
GPS-enabled satellites operate in all weather conditions anywhere in the world, 24 hours a day, no subscription or configuration costs. The U.S. Department of Defense (Usdod) had initially launched some satellites in terrestrial orbit primarily for military use; They were made available for civilian use in the late ’80. Currently there are 31 GPS satellites orbiting the Earth with 3 satellites ready to be launched when needed.
How the GPS came into existence
In 1973, the idea of a Global Positioning System (GPS), initially called Navstar, was developed by the U.S. Department of Defense (Usdod). As mentioned,this technology was primarily for military use and was later made available for civilian use in the late 1980. The GPS technology owes its progress and advances to three people who are recognized by the scientific community to have been clearly associated with the invention of this revolutionary technology.
Roger L. Easton, former head of the branch of spatial application of the Naval Research Laboratory, has been the mastermind behind several engineering applications and technologies that have led to the development of GPS. Another fixture in the development of GPS was Ivan obtaining, who was the founding president of the aerospace company in the United States. It is attributed to the improvement of the satellite system to allow precise data in the monitoring and monitoring of mobile objects on Earth ranging from vehicles to missiles. Another device in the GPS field is Bradford Parkinson, commonly known as ‘ the father of GPS ‘; Bradford was the leading designer and implementer of GPS in terms of evolution and engineering development.
How GPS Works
There are a total of 31 satellites revolving around the Earth in their predetermined orbits. At a given moment on the planet, there is a minimum of 4 GPS satellites that focus on a geographic area given on planet Earth. Each GPS enabled satellite photographs and stationery as well as moving objects and then transmits data on the current location of objects, movement speed, and video-time at regular intervals of time. These GPS-enabled satellites transmit data signals to GPS receivers on multiple telephones at the speed of light: digitized data is detected by the handheld GPS receiver and translated into visual images; The receiver receivers compute the orbital distance of the satellite based on the time interval of the received digital data, which is between the data transmission and the data reception. Once the handset receivers acquire all the information from the orbital satellites centered in that particular geographic area, the GPS receiver can identify the exact location of the terrestrial objects/s that can be stationary or mobile. Using a process called trilateation. The more satellites focusing on the given area, the more exactly the positions, images and speeds can be determined.
What is GPS tracking
GPS tracking is monitoring of precise locations through the use of GPS technology in order to monitor and track the location and travel routes of one or more objects. GPS Tracking is of great value to the police, firefighters, military personnel and businesses requiring constant monitoring of mobile objects such as vehicles, missiles and individuals. GPS tracking systems typically use automatic vehicle locator (AVL) systems that use a network of vehicles, each of which is installed with a portable radio receiver, a GPS receiver, and a GPS antenna. In addition, GPS technology uses interactive maps instead of static maps to determine current road and road situations. GPS-enabled smartphones and other portable devices are often used to monitor and monitor specific objects.
