In this new age of
technology, everything comes at ease, in the earlier times a road trip was not
the most ideal thing to do, as visiting a new place, meant unknown roads and no
directions, although, technology had it all sorted with the help of GPS navigation
systems, before discussing this any
further, do you know what GPS is??
GPS is the globe’s first ever satellite direction
finding or navigating system. It was developed by the defense department of
United States government. The GPS system
consists of 3 important points:
Monitoring station on earth, Satellites in the
space, and your own GPS recipient.
The monitoring station on earth are as
follows: Diego Grcia Atoll in the Indian
ocean and Kwajalein the pacific ocean, the United States have around for
unmanned stations, and the chief master station is in Colorado springs. So basically there are five total monitoring
stations overall.
Satellites in space: the GPS system consists of 24 overall
satellites that loops planet earth in 6 orbit path, that sends out broadcasting
signals from their respective positions in an elevated orbit, which is around
12, 650 miles per 20, 350 kilometers beyond our head. Due to this elevation,
every signal of the satellite is supposed to cover a large vicinity of the surface
of the earth and their orbit is being set up and systematized in a way that
your GPS equipment or recipient on earth is at all times receiving signals from
around 3 to 4 satellites, basically the figure you require to identify your
position.
GPS receiver: your GPS recipient or receiver is
supposed to catch the signals from these GPS satellites to determine your
position or location. The preceding, but most important step in this particular
process is, by default, building up utilization of the information provided.
So, now the question arises as to how to choose
these portable GPS navigation systems?
In this world which is dependent totally on
technology, and with the expansion and growth in the GPS navigation systems,
choosing a portable navigation system for your car or convoy is just the matter
of cost, convenience and features. The best buy online store will be the safest
option to purchase a navigation system, as you have convenience in purchasing
online.
Following are the key points while choosing a
navigation system:
Incorporated battery expediency: the
battery in the device should last for the least of four to five hours on a
single charge.
Routing functionalities: your
center of attention needs to be on the functionality of the device and you also
need to learn and know about how the other consumers who have already used the
device have rated it on the basis of its map database reporting and features
Size of unit: it is better if the unit is highly
portable. There has been a fall in the size of units from the time portable
device came into being. At least of 3.5 inch display should be decent enough,
and also another point to keep in mind it the Text to speech ability.
