How GPS Tracking Devices Have Become Part of Everyday Life

GPS (Global Positioning System) technology was first introduced by the U.S. Military in the 1970s. It was purely designed for the military, but this restriction was removed in the 1980s. This meant that civilians all over the world could suddenly access GPS tracking solutions. Various amazing civilian applications were developed as a result.

How Does a GPS Tracking System Work?

A GPS system can be used anywhere on the planet, in the air, at sea, or on land. Every 12 hours, at least 24 active GPS satellites will orbit the planet. Each of these sends out a radio signal, which allows the system to spot a location but also the system’s direction of travel and speed. The world is covered completely by GPS satellite constellations, each of the six orbital planes being covered by four satellites.

How Accurate Is GPS?

There are various horror stories of people ending up in the middle of a field when using their TomTom. The reality is that the accuracy depends on how good the signal is between the sender and the receiver. The fewer obstacles that are in the way, the better the signal will be. It is recommended, therefore, to switch the device on in a wide and open area and stand still until the signal is picked up. This usually takes between 60 to 80 milliseconds.

How Can You Use a GPS System?

GPS systems can be used in a variety of different ways. For many, they are one of the greatest technological advances of our times. It has helped us to track everything from animal movements to cars. The technology can be fitted into tiny gadgets like smartphones or widgets and it is also highly affordable. This means everybody all over the world is able to access them. Some of the applications of these systems include:

  1. Aviation. Indeed, aircraft pilots depend on these systems to be able to get them to their destination. They help to track their destination but also help them on their airport approach.
  2. Fleet tracking. Businesses with fleets use these systems to make sure that they know exactly where each vehicle is, and where their employees are as well.
  3. Environment. During natural disasters, GPS systems are absolutely vital. They help to survey the affected area, mapping how natural disasters like storms, oil spills, and wildfires spread.
  4. Rail. GPS systems are vital to finding trains, stopping collisions from occurring, making sure the rail system moves properly, and to avoid delays.
  5. Surveying. Traditional surveying would take a very long time, because it was difficult to find a set point of reference. This is no longer an issue now. Defining property lines has never been easier, but more complex tasks, including how to build infrastructure in an urban area, can also use the technology.
  6. People tracking. More and more parents use the technology to find out where their children are at all times.
  7. Route planning. GPS systems make it easier than ever to find out exactly where you are and where you are going.
