General description of what 
GPS is and how it works.

GPS  (Global  Positioning  System)  is  the  only  system  today 

able  to  show  you  your  exact  position  on  the  Earth  anytime, 

in  any  weather,  anywhere.  GPS  satellites,  24  in  all,  orbit  at 

11,000  nautical  miles  above  the  Earth.  They  are 

continuously  monitored  by  ground  stations  located 

worldwide.  The  satellites  transmit  signals  that  can  be 

detected by anyone with a GPS receiver. Using the receiver, 

you can determine your location with great precision.

The satellites are positioned so that we can receive signals 

from six of them nearly 100 percent of the time at any point 

on  Earth.  You  need  that  many  signals  to  get  the  best 

position  information.  Satellites  are  equipped  with  very 

precise  clocks  that  keep  accurate  time  to  within  three 

nanoseconds-  that's  0.000000003,  or  three  billionths  of  a 

second.  This  precision  timing  is  important  because  the 

receiver  must  determine  exactly  how  long  it  take  s  for 

signals to travel from each GPS satellite. The receiver uses 

this information to calculate its position.
