ADVENTURE
Lesson 1 GPS
Have you ever been hiking in the mountains and gotten
lost? What did you do? Did you have a compass to guide
you? Did you have a map but didn’t know where you were
on it? If this has ever happened to you, then perhaps you
should buy a GPS device to assist you.
The Global Positioning System, GPS, is used to tell you
where you are. A GPS device uses signals from satellites to
calculate its position . The more satellite signals, the more
accurate it is. They are very accurate and can pinpoint a
position to within 5 meters.
GPS is used in many applications these days. One of
these is satellite navigation devices. These devices use your
position to show where you are on a map. They also can
navigate for you. You just tell the device where you want to
go and it will guide you. They are great for using in cars
8 Lesson 1
hike map
calculate position
accurate landmark
when traveling to new places, especially when traveling in directions common sense
other countries which use different languages. However, they
can sometimes take the adventure out of getting lost.
The military uses GPS for guiding missiles. Scientists
use GPS for many experiments such as studying
earthquakes. Planes and ships use GPS to navigate. People
searching for sunken treasure at sea can pinpoint their
location, so they can go back later and gather any treasure
found. There are no landmarks at sea, so GPS is very useful.
Relying only on a satellite navigation device for travel
or hiking can sometimes be dangerous. Sometimes the maps
or directions given are wrong or not a good choice. Some
people have died because of this. Clearly, when relying on
devices, you should also use your common sense . Mostly
though, GPS is a great tool for getting around and having
adventures.
