Global Positioning System (GPS) was first conceived and developed by the U. S. DOD (Defense Department) in the 1970s as a way to track the movement and let the enemy know where the military has been all the time. 24 orbiting satellites to make their system and orbit the earth twice a day. Initially the system is purely intended for military use, but Ronald Reagan, and U. S. President, announced that they will be available for civilian use as well, after Kal Korean Airlines 007 shot down by Russian fighter jets during strayed into Soviet airspace restrictions - so you can thank Ronnie's possible for you to have a secret vehicle GPS monitoring device, because no t only the GPS can not be done.
GPS Timeline
In 1978 the experimental Block I satellite was first launched.
In 1983 to take pictures in 007 after he jumped Kal airspace constraints in Russia because of navigation errors, led by Ronald Reagan decided that the system will eventually be available to all military and civilian use.
In early 1993 operating system eventually reaches capacity.
In 1994 the last of 24 satellites placed in orbit eventually.
In 1995, after nearly 20 years, leaving expressed as fully operational.
U. S. In 1996 President Bill Clinton gave instruction to the GPS system available for civilian and military.
How GPS Works
All the 24 satellites that circle the earth leaving the preset orbit in two days. They send signals to ground stations which plots the right time signal is sent, the position of the satellite orbit and satellite Proximity other things. Weapons and information from these signals, the GPS receiver can work out of his position within 10 meters. Well that's not true, because the demand signals from 3 satellite GPS device to find 2-dimensional position (latitude and longitude), and 4 satellites to calculate the 3-dimensional position (longitude, latitude and altitude), using the triangulation plot.
Despite the large resources in terms of time and money that has poured into the form of GPS system, free to use and without constraints. Equipment for when you secret GPS vehicle monitoring, you pay for the development and manufacture of equipment that you receive, not to use abandoned.
