Technology switched from tracking Doppler shifts to using triangulation and signal timing. The longer a signal took to reach a GPS receiver, the farther away the satellite was at the moment the signal was sent. Some of these satellites, starting in , carried sensors designed to detect the launch or detonation of nuclear devices. Although a global positioning system had been inaugurated in , it was highly secretive and strictly the preserve of the US military.
But shortly after the Russians shot down Korean Air flight , killing people, after it wandered off course into Soviet airspace over the Kamchatka Peninsula, President Reagan offered to let all civilian commercial aircraft use the global positioning system to improve navigation and air safety. By , the US government contracted with private corporations to develop airborne, shipboard, and portable GPS receivers.
A project to create a miniature GPS receiver successfully ended in , replacing the previous kilogram military receivers with a 1. However, the Defense Department feared that military adversaries might use the system to their advantage. In , they decided to deliberately decrease the accuracy of the system. In December , the global positioning system achieved initial operational capability for the military, and the satellite system in orbit became fully operational in early Surprisingly, it was in the year when a mobile phone manufacturer, Benefon, launched the first commercially available GPS phone, a safety phone called the Benefon Esc!
By the start of the 21st century, the Department of Defense ended the purposeful degradation of GPS accuracy, which it implemented in Overnight, GPS became ten times more accurate, and all kinds of industries — from fishing to forestry and freight management — soon began using it. This began the era when GPS receiver technology became much smaller, cheaper, and more accessible that private companies began producing personal GPS products.
During this time, cellphones and tablets progressed right along with the use of GPS navigation technology.
GPS Tracking Software
Mobile phones were able to perform GPS navigation and tracking processes using apps. More and more commercial vehicles were also equipped with dashboard computerized systems and communications platforms, such as Qualcomm, Tom Tom, and Garvin. By the mids, GPS navigation technology had evolved into tracking systems. This was in part due to the improvements of machine to machine M2M communications, which is the predecessor to the Internet of Things IoT. As GPS tracking became increasingly accurate, so did cloud-based technology and sensor parameters.
By , high-quality GPS receivers were able to provide horizontal accuracy of better than 11 feet.

At present, the US Air Force manages a constellation of 31 operational GPS satellites, plus three decommissioned satellites that can be reactivated if needed. Today, GPS is a radionavigation system owned by the US Government and operated by the United States Air Force to meet national defense, homeland security, civil, commercial, and scientific needs. In the age of the internet, it has been used as receivers for directions and for navigation apps that tell us where we are and how to move between points. Still, it is extensively used in aviation, the military, and marine navigation.
Various other industries continue to benefit from the technology as well due to its ability to decrease operating costs and increase productivity and proficiency. Most importantly, it provides everyone an extra layer of security to protect both loved ones and assets.
Here are just a few of the industries benefiting from GPS. This sector has been using GPS devices to operate. Farmers have a specific season for planting, weeding, and harvesting. Taking advantage of the patterns of seasons, they put GPS receivers on their tractors and other farming equipment. This allows them to map plantations and ensure that they return to precisely the same time when planting or weeding in the next season. This strategy is effective especially in weather with less visibility.
More so, the accuracy that GPS brings makes it suitable for mapping soil sample locations. Modern-day aircraft use GPS receivers to provide real-time aircraft position that pilots and passengers need to know. They also provide a map of various destinations depending on where the aircraft operates. They also use the app to track the aircraft and direct the pilot in the case a change in the weather conditions occur or any other issue arises.
Fleet tracking technology is one of the fastest-growing GPS navigation use cases. GPS fleet trackers help fleet managers determine the location of their vehicles, set up the shortest routes that employees can take for faster delivery, and update drivers with real-time driving directions. More importantly, it enables managers to respond quickly to emergencies and provide accident-tracking roadside assistance. Fleet tracking technology like telematics is exceptionally increasing fleet efficiency. Data on too much acceleration or speeding allows the fleet manager to make informed decisions about training drivers on reducing fuel consumption by driving the vehicle at optimum speed.
GPS devices are now widely used during investigations to catch criminals.

The police also use it to keep track of people who feel that their lives may be in danger. Not only does it provide concrete evidence, GPS tracking devices are safe, efficient, and cost-effective. GPS is used by boat captains to help them navigate through waters to their destinations easier. GPS helps them make sure that the channels are clear. They also use these devices to ensure that there are no obstacles that can hinder navigation. They are even required in marine departments since they are used to map and position dredging operations in rivers, sandbars, and wharves to ensure that other boats are aware of how deep they should get.
The US Department of Defense was the first to develop the GPS app system, and since then, the system has been adopted by numerous military forces around the world. Other countries have even decided to develop their satellite navigation networks as a defense mechanism during war times.
Today, these are used to determine the location of vehicles and missiles, especially during a war. There are many scientific applications of GPS beyond just navigational matters. GPS devices are used in different fields including physics, biology, and earth science. It can be used to help detect structural problems in roads and buildings, as well as predict natural disasters like earthquakes through the monitoring of tectonic plate movement. Scientists around the world have also been using radio signals from GPS satellites to learn more about the atmosphere of our own planet.
It has been used to study wildlife, terrain, and human infrastructure. GPS tracking devices are used by many to track themselves or those that matter to them like their loved ones, pets, and property. Soon after GPS was made available for civilian use, several manufacturers introduced GPS trackers that were intended to allow the tracking of vehicles and other assets. GPS devices are used in the telecommunications industry to provide users with accuracy, reliability, and stability of their operations.
Although clocks can provide this, GPS supports the derivation of synchronized time zones with the help of the satellite signals. Passive GPS and active GPS are equally beneficial and have both helped users in more ways than one, but the way they work differs. Passive GPS trackers do not give you real-time updates. The information gathered by these devices are stored through an internal memory.
Most passive trackers do not need a monthly fee, so you can expect this to be a more economical option compared to active trackers. Active GPS trackers, on the other hand, process and deliver data in real time. Understandably, active GPS trackers cost more than the passive ones, but the price is justified by the reliable software application that comes along with them and the convenience of being able to access real-time data.
GPS devices are relatively new technology, and the legality of their use may vary by state. Even federal courts are split on how to handle the technology. If you have any legal issues involving a GPS tracking device, you should consult with a criminal lawyer for advice. This is particularly true if you feel that the police have wrongfully used GPS evidence against you. An attorney near you will be able to explain the GPS laws of your state and what sort of rights and remedies you have. For starters, it's entirely legal to use a GPS tracking device on any vehicle or asset you own.
But before you use a GPS tracking device on someone else's person, vehicle, or property, you should do a little research on current federal, state, and local laws. As of now, here's what private citizens need to know about GPS tracking and the law. Over the years, GPS trackers have been used for various reasons and by various types of businesses.
Large and small businesses and people from all walks of life have benefited from this technology, sharing their stories and recommending these devices to their connections.

The GPS tracker reported the position of both men on board the boat and on the island. Overwhelmed with the thefts and losses, the company started adding GPS trackers to their outdoor units. They then set up geofence alerts to be notified when their equipment would exit a specific area, and before they knew it, they were notified that their air conditioning units were not in the same place they had left them.
After following the location from the GPS, they were able to track down 60 other stolen items that were being stored in a warehouse. Dave Crooks, a teacher from Calgary, Alberta, almost regularly misplaced his iPhone in his house.
In order to avoid completely losing it, he installed a GPS tracker on his device. One time, his phone was stolen together with his car keys and wallet.
Thanks to the GPS device installed on his iPhone, he was able to trace it. He immediately called You can then log on to the internet via a desktop computer or mobile device and see exactly where your vehicle is located. Our GPS trackers have strong receivers that are accurate to approximately 6 ft. The devices update between every seconds while the vehicle is moving.
With our custom algorithms, we deploy multiple techniques to conserve data while keeping the GPS tracking as accurate as possible.
