Global Positioning System, popularly known as GPS, is a technology used to obtain accurate positioning, navigation, and timing (PNT) measurements with the help of satellites orbiting the earth. Business corporations use GPS systems to track assets, transportation companies to monitor their fleet, and weather stations to evaluate weather changes. In fact, even our cellphones have GPS. Read on to find out how the technology works and the benefits of using GPS devices.
How does GPS work
A GPS system comprises three essential components: satellites orbiting the earth, ground stations, and a receiver (your mobile phone). As you might be aware, several satellites orbit the earth and continuously emit signals that hold crucial data about location, time, etc., by mapping longitude and latitude. A receiver, such as your mobile phone or other GPS devices, connects to the satellites and intercepts these signals. So, what do ground stations do? They only ensure the satellites are in the right place at the right time for accurate data.
Benefits of using GPS devices
GPS tracking is multidimensional; it can be used for professional and personal use. Businesses use it in operational procedures to locate assets. On the other hand, most individuals use it to reach a particular destination or learn about the weather. Irrespective, GPS devices help save time and improve efficiency. The following are the top reasons for using the technology:
Helps track location
Many companies worldwide use GPS devices to secure their assets by tracking their location. Even individuals use it to track valuables like cars, luggage, etc. Some GPS systems come in the form of wearable devices. This is especially helpful to track the location of seniors who stay alone or pets who tend to wander away. Even travelers use such devices to keep their families aware of their location in an emergency. It assures individuals that their valuables and loved ones are safe.
Reduces costs
Satellites that transmit signals to GPS devices and other supporting infrastructure are operated and maintained by the US defense department. Thus, the system is free of cost. However, you require a device, such as a mobile phone or transmitter, to avail of the benefits. Smartphones and laptops use maps through GPS, typically for free, anywhere in the world. Also, GPS is unlikely to be privatized in the future.
Protects against crime
GPS devices are valuable gadgets that help track terrorists, criminals, thieves, and other defaulters. This makes people feel safe from criminals and discourages them from becoming one themselves. The police sometimes affix tracking devices on suspicious vehicles to track the places they go. It also allows for the quicker mobilization of police cars during an emergency.
Offers flexible route options
Since the dawn of GPS devices, traveling has become easy and convenient. GPS provides different route choices with traffic visibility, and the time it should take to get to a location using a particular route. You can choose the best possible route to arrive at the destination faster. And if you take a wrong turn, no problem! The GPS tracking system shows new routes from your current location. But using this system requires a little skill and understanding.
Assists the military
While GPS devices are helpful for business and daily use, they also benefit the armed forces. Military officers use GPS to target and guide missiles. Higher accuracy lowers collateral destruction. GPS also helps measure the distance between two points on the map, helping officers to plan operations.
Predicts natural calamities
Beyond navigational use, GPS devices help in scientific fields. Various scientific applications help detect structural issues in buildings and roads. They also help predict natural calamities. It is made possible by monitoring tectonic plates’ movement in the earth’s lithosphere. Teams can track this with GPS and save lives.
Provides traffic and weather alerts
The best thing about GPS devices is that it works in real-time. That means while the device is still in use, it keeps updating information. For example, you would get a notification of a road blockage, accident, or climatic alert at a particular destination and second-by-second updates thereafter on how the situation is progressing. These alerts ensure safety. Weather alerts are also helpful for welfare and disaster relief teams to prepare for any eventuality.
GPS devices tell you where you are on the globe and the route to your destination while traveling from place to place. It traces distance, sunset, sunrise, obstacles on roads, highways, and other details. With recent advancements, GPS has become more accurate, and you can easily find any address on the planet.
