GPS technology explained.
The Global Positioning System (GPS) is a satellite-based navigation system made
up of a network of satellites placed into orbit. GPS works in any weather
conditions, anywhere in the world, 24 hours a day. There are no subscription fees
or setup charges to use GPS.
GPS satellites circle the earth in a very precise orbit and transmit signal information
to earth. GPS receivers take this information to calculate the user's exact location.
This location is then passed on to the software, which displays in real time the
maps relevant to the location.
Once the user's position has been determined, the GPS unit can calculate other
information, such as speed, bearing, track, trip distance, distance to destination
and more.
Today's GPS receivers with parallel multi-channel design are extremely accurate.
A GPS with a 12 parallel channel receiver is quick to lock onto satellites when first
turned on and maintains a strong signal whilst driving.
