GPS Receiver Makes Being Lost Difficult
Getting lost and staying lost is becoming more difficult
everyday as the price of a GPS receiver has fallen drastically over the past
decade to enable just about everyone to have one. Hunters, travelers and even
construction workers have use for a GPS receiver, however knowing how to
interpret the information will determine just how valuable it is to carry.
Two dozen working satellites, plus a few spares, are
circling the globe over 12,000 miles up, continually sending signals to the
ground. By checking the current time, the distance between the satellite and
the GPS receiver as well as altitude, the receiver can offer a location on the
ground. By receiving information from four or more satellites the location can
be even more exact as the overlapping information will allow the GPS receiver
to find a probable location based on information from multiple sources.
While signals from a global position satellite are traveling
a long distance to reach the GPS receiver units, there are some barriers to the
signals getting through. Parking garages, for example, may block the signals
and storm activity may slow the signal down causing locations to be slightly
off track.
GPS Receiver Part Of Larger Units
Those hiking through the wilderness, such as hunters, may
lose their bearings and having a GPS receiver with them can help them find
their way back home. Travelers like the fact that their car system can tell
them where they are if they get lost, and if they subscribe to a navigational
service, can quickly find the directions to get back on their intended route.
Construction workers count on their high-tech GPS receiver
to pinpoint their location by accepting signals from up to 20 different
satellites. This gives a much more accurate location and when looking for
property boundaries, this can save a lot of time for construction. It can also
help in locating underground utility lines and prevent them from being damaged
during digging.
Many businesses will have a GPS receiver in their office to
help keep track of their vehicles, if equipped with tracking devices, and also
keep track of shipments to better determine estimated arrival times. They can
also use this equipment should a vehicle become lost or stolen on its route.
For persons traveling a GPS receiver can help if they get
lost. By calling local authorities they give them their current location and
get directions to where they need to go.
