GPS Technology: Mo’ Saci Science in Action (Magic and Science)

Let’s elaborate on the GPS. It’s called Global Positioning System. The system consists of a collection of satellites orbiting the Earth equipped to determine the location of an object, place, or people respectively. In contrast, GPS has been used for various purposes, such as military exercises providing direction to motorists for navigation. The GPS comprises three important segments:

  1. Space Segment – Also called “Satellites”—It consists of a Constellation Arrangement of 24 satellites that transmit radio signals (one-way) to the users, providing them with position and time. These satellites fly under the MEO (Medium Earth Orbit) zone and orbit the Earth two times a day. The operational satellites are a mixture of both old and new satellites to strengthen the medium of signal transmission.
  2. Control Segment –Also called “Ground Control”—It is a globally synchronized control station that ensures the satellites are orbiting the Earth and following the signal commands accordingly. In simple terms, the Control Segment in GPS monitors the satellites’ navigational data, updates it, and keeps an eye on its satellites’ health and status. Control Segment is a global network that works on the principles of TMAC—Track, Monitor, Analyze, and Command.
  3. User Segment – Best known as “User Equipment”—It is a receiver-type device (a GPS Receiver equipment), that receives the one-way transmitted signals from the satellites. With the received data, User Segment calculates the position and time to further map it on a three-dimensional coordinate.

Sounds complicated? Let’s put it that way. GPS is a utility that helps civilians and military personnel track and monitors the position and time of anyone and anything.
And so, you know, there’s a difference between GPS technology and GPS tracker—and it’s not rocket science. GPS technology is a navigational services provider whereas GPS tracker is a highly refined branch of GPS. Now, the question that must have popped into your mind is…

GPS Tracking

What is a GPS Tracker and how does it work?

As the name should ring some bells, a GPS tracker is a tracking device used widely around the world for the determination of location through satellites. It operates under the ‘Trilateration’ process—a technique that calculates longitude, latitude, velocity, time, and elevation. Trilateration works simultaneously with three or more GNSS (Global Navigation Satellite System) satellites to produce accurate results. The short and not-so-geeky definition of a GPS tracker is, that a GPS tracker is a device that connects to satellites, receives signals and tracks locations.

The majority population is familiar with popular uses for GPS technology, including mapping, directions, surveys, receiving recommendations, and tracking children. In contrast, Police, military, and various other government department utilize GPS apps for private and commercial purposes.

It requires a device for tracking placed in the vehicle to an asset respectively. However, the tracking device sends coordinates about its precise location and reports where the valuables and cars are. In addition tracks the movement of vehicles, individuals, and assets, respectively. Nonetheless, GPS trackers pinpoint the accurate location of the dispatched truck, route, and commodity transported.

A word of Clarification: GPS Trilateration is way different than Triangulation, which only measures angles and not position or distances.

If you happen to have a GPS tracker or want to buy one, here’s how a GPS tracker works.

GPS trackers come in various types, supporting the ways of their utilization. Let’s take vehicles, for instance, some GPS trackers receive power from the vehicle’s electrical system to operate. The device collects information from the car as it runs on the road and then transmits the data to the GPS receiver.

Throughout the years, GPS has proven to be the most dependable technology to benefit its users with precise tracking services. As we take steps towards prosperity, GPS ensures to be around us in various embedded and digitized forms. Learn more about the modernization of GPS.


GPS tracking utilizes the Global Navigation Satellite System (GNSS). However, the network consists of satellites sending coordinates to GPS devices directly about the current location, travel movement, time and speed of vehicle and object. Two GPS developers were awarded The National Academy of Engineering Charles Stark Draper Prize in 2003. Ivan Getting, emeritus president of The Aerospace Corporation and engineer at the Massachusetts Institute of Technology, developed the basis of GPS and made improvements to GPS’ predecessor, the World War II land-based radio system known as LORAN (Long-range radio aid to navigation). Bradford Parkinson, professor of aerospace and astronautics at Stanford University, conceived the current satellite-based system in the early 1960s and created it with the help of the U.S. Air Force. A GPS creator, Roger L. Easton, was awarded the National Medal of Technology on February 13, 2006, at the White House. In February of 1993, the National Aeronautic Association selected the Global Positioning System Team as winners of the 1992 Robert J. Collier Trophy, The most prestigious aviation prize in the United States.

  • Routes Accuracy: GPS-based tracking devices help to plan the fleet’s routes. In addition, it’s user-friendly and assists in locating and identification of drivers for specific tasks. At the same time, it saves the hassle, ensuring full customer satisfaction.
  • Less Operational Cost: GPS tracking devices assist in making cost reduction and provides data that is updated in real-time. However, With increased information and understanding of the operating fleet, GPS tracking provides accurate information that helps make strategic business decisions.
  • Fuel Cost Saving: Using GPS tracking in dispatching, you can reduce excess fuel use, save time, and cut emissions. Exemplify that GPS technology can be used to track vehicle speed. It helps to assess and advise fuel-saving behavior. On the road, you can share information and suggest shorter routes.

A GPS vehicle tracker can locate vehicles and retrieve other assets faster than in a blink of an eye. In contrast, you can use geofence around assets and vehicles with GPS security and get yourself notified whenever a vehicle leaves the designated area, moreover, if it’s moved outside of assigned hours.

With better trip management and electronic time logs, you’ll be able better allocate resources based on real-time data you keep your driver’s hours of payroll under control. Timesheet fraud occurs when drivers are paid for undone work.

GPS tracking systems might work in different ways. Commercial firms’ GPS systems are usually used for vehicle monitoring during journeys. However, certain systems can archive data within GPS called passive tracking. Moreover, systems transmit data into a database through a two-way GPS modem.

The GPS tracker on passive devices keeps track of places and records details of trips made at specific times. In contrast, it also updates device behaviour from the past 12 hours. Its information gets stored in a memory stick and can later be transferred to a computer. Furthermore, its certain features automatically download and establish a time. Sometimes it may be downloaded regularly during the journey.

Passive GPS is used to describe real-time tracking systems that send direct coordinates to a tracking website. A passive GPS is used in numerous commercial applications monitoring children and elderly individuals. Keeps the caretaker aware of the location. Contrastingly also used to monitor employees’ actions during work and the operation of fleets.

History of the GPS

The GPS, as we know it today, is a culmination of various technological advancements and strategic decisions. Let’s trace its evolution:

  • 1978: The journey began with the launch of the first Block-I-based GPS satellite in February. Initially produced by Rockwell International, Lockheed Martin later took over its manufacturing.
  • 1983: Following the tragic incident where a Soviet interceptor aircraft shot down a Korean airliner, U.S. President Ronald Reagan announced the intention to make GPS accessible to civilians once it was fully operational.
  • 1985: To further the system’s development, ten experimental Block-I satellites were launched, providing crucial data for improvements.
  • 1989: “Old Satellite Orbiting Earth”, one of the pioneering Block-II satellites, was set into orbit on February 14. Notably, the first of its kind to resemble modern-day GPS satellites.
