For the simple reason that atomic clocks are highly accurate - usually only gaining or losing one second over thousands of years. High accuracy is vital in GPS systems - otherwise the maps would be out of alignment as you travelled.
As an example - One of the most recent atomic clocks constructed in 2010 is reckoned to only gain or lose less than a second in over a billion years !

What is a main reason for the film 'Inconvenient Truth' was made?
To make people aware of global warming.
How do you reset the time on an atomic clock when daylight savings time ends?
You don't do a thing!! My husband replaced the batteries on our the other night, and after a few minutes (I assume it got a radio signal update) it reset itself! Pretty cool... You are wrong!!!!! I asked for a manual reset, not waiting for the clock to maybe catch up.
One reason for global warming is?
One reason for global warming is the greenhouse effect. Cars and factories emit gases such as Carbon Dioxide and Carbon Monoxide. When in the atmosphere, these gases trap and retain the Sun's heat making the overall average temperature of the earth rise. This leads to other problems.
What two things does the atomic mass represent?
Atomic mass is the sum of the number of protons and neutrons in the nucleus. The reason it is typically found in decimal form is because it is using the average number of neutrons, from all the different isotopes of that element.
Which is not a reason why the mass of an atom is expressed in atomic mass units rather than in grams?
The main reason the mass of an atom is expressed in atomic mass units rather than in grams is that the mass of an individual atom is extremely small, typically in the range of 10^-23 grams. Using grams would result in cumbersome decimal numbers, while atomic mass units simplify calculations and comparisons of atomic mass.
What was the reason for the development of the GPS system?
The military needed a global positioning system to locate people and equipment and to steer intelligent munitions.
Why is clocks called clock?
I wouldn't say the inventor, had a reason for calling clocks clocks, the person in which invented clocks came up with the name himself
Why are clocks circle?
Unfortunately, not all clocks are circular. The reason that most clocks are circular is because of convenience. As clocks rely on the rotation of the hands to tell time, it is simply easier for the numbers to be arranged in a circular formation around it.
Why is clocks called clocks?
The term "clocks" likely comes from the Middle English word "clokke," which originated from the Latin word "clocca" meaning "bell." Clocks used to primarily consist of mechanisms with bells to indicate time, thus the name stuck.
Is US the reason you have global warming?
No. Humans are the reason for Global Warming! Humans in big rich countries!
What was the reason why Big Ben was built?
cause they didnt have clocks then and they only built one
Why are satellite 12000 miles in the air?
Navigation is a reason for why satellites are 12,000 miles in the air. The purpose of the satellite will determine its location in the atmosphere, with global positioning for the United States of America and GLONASS for the Russian Federation claiming altitudes of 6,000 to 12,000 miles.
Is Global warming affecting canadians?
It's called global warming for a reason...
Why are dial clocks better than digital clocks?
Well, one reason is that if digital replaces dial.... people won't know the difference between clockwise and counter clockwise. :)
Reason against using the atomic bombs?
They kill.
