The Historical past of GPS Technology

The Historical past of GPS Technology

With GPS equipment now in hundreds of thousands of cars and trucks, cell phones and purses close to the place, it is tricky to consider that only a ten years ago, the technology was employed almost solely by substantial corporations and the armed forces. But time has moved quickly for World wide Positioning Systems, which tends to make feeling offered that the story of GPS’ historical past begins with a evaluate of time.

It all starts with TIME

GPS technology exists these days simply because researchers sought a way to evaluate time extra precisely than it experienced ever been calculated just before. And so, they produced the Atomic Clock, a super-exact machine that evaluate the time in a billionth of a 2nd.

But the Atomic Clock was not created in purchase to continue to keep researchers from staying late for supper. They employed the precision of the clock to test Einstein’s concept of relativity as it pertained to time and area.

Utilizing Atomic Clocks to evaluate time and area

With these atomic clocks, researchers and engineers found that there had been slight discrepancies in time close to the globe. They started to position the clocks just about everywhere from Mount Everest to the Gobi Desert and then seemed for very small variances in the time in just about every of the spots. This information and facts assisted validate Einstein’s perspective of the universe and would soon turn out to be a critical part of satellite technology.

Sputnik and the creation of a armed forces GPS method

When the Russians launched Sputnik in the 1950’s, researchers speedily learned that the satellite could be employed to track spots on the ground by beaming a signal up to the satellite – and obtaining a reaction returned to Earth. How that concept traveled established the location of the satellite relative to a place on the planet.

The US Navy soon started launching satellites of their own, and employed them in critical armed forces actions to assistance troops engage in the appropriate struggle spots and help substantial ships circumnavigating the globe.

Following a time, Navy engineers understood that adequate satellites, positioned in very certain positions with an orbit close to the earth, would build a crystal clear photograph of our planet – and that this “picture” could be employed map out individual factors close to the globe with beautiful precision.

Completion of the Procedure

In 1993, it all came with each other. The United States Navy launched the 24th of 24 diligently positioned satellites into orbit – and the World wide Positioning Procedure was born. The satellites are positioned in this kind of a way that now everyone with an low-cost GPS machine can locate their position (or an additional location) any place on the planet. And to feel, it all started with Einstein and a group of researchers who desired to come across the top evaluate of time.

Right now GPS equipment are a practical software for lots of People. The technology has turn out to be very very affordable and assists persons get hold of appropriate instructions to their location although applying a minimal total of gas or time. And if a person experienced instructed you 20 yrs ago that GPS technology would be a “hot Christmas gift”, probabilities are you wouldn’t have offered them the time of working day.

For evaluations, rates and products information and facts about the most up-to-date GPS equipment for the motor vehicle, cell phone and extra, take a look at At you are going to come across unbiased evaluations, facet by facet products comparisons and all the things else you will need to make an educated purchase – and get the most out of your GPS machine.
