How Does Navigation Work?
How Does Navigation
Work?
Global Positioning System (GPS)
In order to navigate you to your destination, your TomTom GO must know
where you are now. To find your current position, your TomTom GO uses the
Global Positioning System (GPS). GPS is available for free and without
subscription.
GPS uses satellites to transmit signals to GPS receivers. Your TomTom GO
has a built-in GPS receiver. Using the GPS signal, your TomTom GO can work
out where you are and how fast you are going. GPS signals work in all
weather, anywhere in the world.
Finding your position faster
If you use your TomTom GO in combination with TomTom HOME, your GO
will download information about where the GPS satellites are going to be for
the next 24 hours.
With this information, your GO will be able to find your current position very
quickly when it is first switched on.
Maps
Once your GO knows where you are and you have told it where you want to
go, it uses the digital map on the memory card or hard disk to work out the
best route to your destination.
Note: Your TomTom GO does not transmit your position, so others cannot
use it to track you while you are driving. You can however send your
position to TomTom Buddies. For more information, visit
