Ancient history reminds us of people who have traveled and explored the world. Even up to this day, man never stops exploring the universe. These travelers just wouldn’t stop trying to find out some discoveries that they are also willing to share to the world. When before, men use natural instruments to guide them in their travel, today men created the GPS technology to help them track their travel and location more accurately.

Almost all of the best places in the world have already been explored (or so we thought). Man’s intellect has led into the discovery of the instrument called compass. With the use of navigational compass coupled with the ability to read maps, man can already find his away around in case he gets lost or is not familiar with a certain place.

With the introduction of Global Positioning System technology, compass and map reading somehow made a little back seat. Just a little background information, though, GPS technology was once conceived for use only in the military. In 1980s, however, this technology was already shared to the public.

Today, in recent times, tracking one’s position or location is very possible and doable with GPS satellites feeding the receiver with data. Aside from physical location or position getting tracked, GPS also has the ability to accurately track speed during the travel. With the basis of the speed being tracked, GPS can also provide details of arrival time.

Some GPS units are also loaded with maps depending on the purpose; it can be a GPS receiver for driving, sailing, hiking, flying, cycling and jogging. If you have a GPS unit that isn’t loaded with your specific map then you can easily purchase and download that particular map online. There are even maps that are provided for free online.
