GPS Trackers Can Save Your Business Thousands Of Dollars

GPS Tracking

With GPS tracker can save your business thousands of dollars and help streamline efficiency. How? By helping you track and manage all assets remotely. Quickly and easily locate lost or stolen equipment and reduce unnecessary delivery or transit detours. For delivery, transportation, or businesses that move or transport assets, GPS Trackers can help save on fuel costs and increase efficiency. You can effectively monitor your fleet and cut down on idle time in order to find the most efficient route for delivery, service, or transit. This applies to both transporting goods and keeping an eye on employees. With a GPS Tracker you can more effectively monitor and manage your employees helping you identify problems or delays. Perfect for people in the jewelry industry, construction business, car manufacturers, and any business that ever has important assets in transit.

Cell phone GPS tracking

Cell phone GPS tracking is a little tricky to talk about because mobile phones have GPS-like capabilities without having to be GPS devices.  So, in some cases, a cell phone is able to be tracked even when it doesn’t have a GPS receiver installed in it.  The reason behind this is rather simple and has everything to do with a principle I have already covered on this site: trilateration.

Once you understand the basics behind this principle you will see that is is obvious that a cell phone could be tracked whether or not it was GPS enable.  Simply put, trilateration takes the know distance of an entity from 3 or more objects to calculate the exact location of that entity.  I know, that sounds confusing – but it really isn’t.

Imagine that you are sitting somewhere in a room.  The room is a 10×10 square and you are somewhere in it and you want to find out exactly where you are in the room.  There is a desk in the middle of one of the walls that you are 5 feet from.  On the exact opposite wall there is another table in the middle of the wall that you are exactly 5 feet from as well.  Then there is a mirror on the third wall that you are looking at yourself from 5 feet away.  Where are you in the room?

If you answered, “In the center.”  Then you already know everything you need about trilateration to completely understand how a cell phone can work without actually having a GPS tracking device installed in it.

Let’s use the example of the two table and the mirrors from above to help us understand this.  The tables and the mirrors here represent cell phone towers that are dotted across urban landscapes all over the country.  In my city, they are dressed up to look like palm trees or other pleasant things but you still know what it is, a cell tower.

These cell towers transmit cellular signals out to mobile phones.  The signals travel at a constant speed which makes finding out the distance between cell phones and cell towers very easy.  All one must do is record the amount of time it takes between the time that the signal was transmitted by the tower and when it arrived at the cell phone.  You then take the time that it took and multiply it by the speed at which the signal traveled.  This looks something like this:

Distance Traveled = Speed x Time

This will give you the cell phone’s distance from the cell tower.  Since the cell phone provider (a cell phone provider is a company like Nextel, AT&T, Verizon, TMobile, etc.) knows exactly where they cell tower is, they know that the cell phone is within x number of feet from that tower.  Imagine a big circle surrounding the cell tower in the map in your mind.

Now imagine a second cell tower that also transmits a signal that is picked up by the cell phone.  This is a certain distance from this second cell tower so imagine another circle around this second tower.  Where the two circles intersect are the potential locations of the cell phone as far as the cell phone provider is concerned.

Once you add a third tower in the mix you should have a pretty darn good fix on the location of the cell phone – all without the use of GPS tracking devices.

It is important to understand that this is also exactly how GPS works, but instead of cellular towers on the urban landscape you have satellites in the heavenly firmament  and instead of circles you have spheres around each satellite.  This is pretty amazing stuff if you ask me.

Now that we have learned that cell phones can have GPS tracking without actually having a GPS device installed in it, let’s take a look at what can be done with GPS cell phone tracking.

There are several different applications that should be considered, but we will only take a look at three to give us a flavor of just how awesome this type of technology can be.  Cellphone GPS tracking can be used for navigation purposes, to monitor a loved ones activity, and to learn useful things about your current location.
