How Does A GPS Tracker System Work?

If you watch a lot of action-packed movies or TV series these days you must have been awed by how technology can be applied in so many things like crime investigation and tracking. One technology that is often inserted in so many modern movies is the GPS or Global Positioning System.

This is one huge project of the US Department of Defense that is fully functional and indeed very useful. The most common application is the GPS tracker that is now installed in most modern cars.

GPS Technology

A GPS unit is mainly made up of three segments: the satellites, the control systemand the user.

There are over two-dozen satellites stationed just outside the earth’s atmosphere. These machines are about 11,000 nautical miles above the surface and they are funded and controlled by the US Department of Defense. In order to control these satellites, there are control or monitoring stations in several strategic locations across the globe.

These are the units that get the information from the satellites, monitor, and analyze them for any significance in government operations. The user holds the receiver of the radio signals from the orbiting satellites. It can compute its distance from the satellite by using the time stamps on the radio waves that were sent.

To zoom in to a specific location, four satellites are needed. The accuracy is around 10-15 meters so it doesn’t really help if the object being tracked is a car that is about 3 meters long. This is why there have been upgrades like the Differential GPS, which helps give more accurate information on the precise location of a vehicle.

Application In Cars

The GPS tracker technology has found a lot of use in so many things that need to be tracked. The primary application is in vehicles. With the GPS tracking device installed in the car, the owner is certain that he won’t get lost even in places unknown to him. The screen that is hooked on to the GPS system of his car will help him find his way onto the nearest main road leading to his destination - that is, if he got lost.

The best use for the GPS tracking system is in the unfortunate event that the car gets stolen. If you only have the ordinary alarm system installed, you can’t be sure about your car’s total safety. This is because any skilled car thief can easily override your alarm system and get away with your car - and you will never hear from it again.

The GPS tracker system is a genius of a tracker so your thief can’t really go far with your car. The minute you suspect that it’s been stolen, you can just report to the authorities immediately and they can tap into the GPS system so they can instantly check where your car is at that very instant.

The GPS tracker is also useful in many other ways like:

• Investigating on a cheating spouse
• Monitoring where your teen kids are
• Keeping track of your pets
• Guarding people on parole
• Tracking small units like cell phones

GPS Tracking Devices - Teens vs Parents, Law Enforcement vs Invasion Of Privacy

GPS tracking devices have many beneficial uses. However, controversy over the covert use of this relatively new technology has ethical scholars, right to privacy advocates, law enforcement, and teens and parents at odds with each other.

GPS tracking children devices have a multitude of uses, the majority of them are mostly beneficial. However, GPS devices sometimes involve privacy issues that can, at times, lead to controversy.

Fleet Vehicles and GPS Tracking Devices

You’ll find that there are many companies both large and small that use GPS tracking devices to follow the location of their vehicles. The majority of trucking companies have the capability to tell you where all of their vehicles are at any given point in time. In a similar manner, taxi companies as well as repair companies have the capability to monitor their trucks location so that they can dispatch them in a more efficient manner.

However, there are people that believe this gives the companies who choose to use GPS tracking devices more information than is needed about their drivers. For instance, trucking companies have the capability to know how much time a trucker has spent on the road, when and for what period of time he stops for sleep or meals and if he has taken any unscheduled side trips.

Dispatchers at these companies may be privy to personal information that is none of their business, such as a driver having lunch each day at the same place, and it is not his residence. Some individuals are of the opinion that this constitutes an invasion of personal privacy.

Teens and GPS Tracking Devices

There are some parents who use GPS tracking devices to know the location of their teens. They may download GPS tracking software technology to the mobile phones of their teens, or they may place a GPS tracking device somewhere in their car. The teenagers may or may not be aware that their parents are monitoring them.

There is likely quite a few teens who believe that this is and invasion of their privacy.

GPS Tracking Devices and Surveillance

Does the thought run through your mind if your spouse having an affair? Curious to find out what your brother-in-law is up to? If you place a hidden GPS tracking device on their vehicle, you will at least know where they are going in their car. You may have to come to your own conclusions as to what they are actually doing there.

There are many people who would agree that this would be an invasion of privacy and quite a few would be offended if they either knew or suspected you were tracking them. Things get a little more involved when police use GPS tracking devices.

GPS tracking devices have been used by police to successfully solve crimes. An example of the conflict between serving justice and invasion of privacy; say the police put a GPS tracking device on the car of a person they suspect of being a murderer. They successfully track the the murderer as he unknowingly leads them to the victims grave. Is this an invasion of privacy? Should law enforcement officials be allowed to use GPS tracking devices this way?

If, for instance, the police need to obtain a search warrant from a judge to use a GPS tracking device, should a private citizen be able to use this technology without a warrant? Should the average private citizen even be allowed to use GPS tracking device technology at all? At times the right to privacy and the right to information are in conflict, this is one of those time.

All technology has moral and ethical implications that we as individuals and society as a whole has to grapple with. The right to privacy is the ethical dilemma we are forced to deal with when we use GPS tracking device technology.
