History of GPS Tracking
Once President Ronald Reagan issued the directive making GPS freely available for civilian use in the 1980′s, the evolutionary wheels began to turn. The early years of commercial use, up to and including the 1990′s, were limited due to several factors. This included a limited number of GPS chip manufacturers, antiquated and costly microprocessor technology, and an intentionally degraded signal called Selective Availability. The highest quality signals were reserved for the U.S. military while the civilian market was left with a significant variation. The net results were high-cost devices, limited capability, and bulky equipment. At that time, these devices were limited to law enforcement agencies and those willing to sacrifice performance at a high price. The new millennium ushered in an incredible transformation in the GPS tracking industry. President Bill Clinton ordered Selective Availability turned off at midnight on May 1st, 2000. This allowed developers to provide ultra-sensitive and accurate GPS tracking data we see in today’s market.
Three key technologies come together and complement GPS-enabled devices. All three have gone through incredible development growth phases that coincidentally have come together nicely. The microprocessor industry has produced devices that are smaller, faster, and more powerful. Microprocessors provide a platform for system integrators and manufacturers. Since GPS satellites transmit unidirectional signals, customers such as fleet tracking that need to locate assets remotely depend on telecommunications and/or communication satellites. Cellular data communications or General Packet Radio Service (GPRS) is the most common method of viewing remote GPS devices. This is because the cost of cellular data is much more cost-effective than satellite communications. As experienced in the GPS and microprocessor industries, cellular communications have become a reliable and preferred method in mobility.
Fast-forwarding to today, GPS tracking technology has become a staple of daily living. The most popular use, of course, is in-vehicle navigation with many portable versions retailing under $ 100. Many current uses of GPS tracking are transparent to many of us. GPS tracking technology can be found in our cell phones, electric meters attached to our homes, etc. The cost to add GPS receivers in today’s electronics is minimal and provides a manufacturer with a competitive edge. Because of this, more and more devices are equipped with beneficial product features. Although millions of people benefit from GPS tracking technology, law enforcement agencies have become dependent on it. GPS tracking devices help lower their operational costs and provide an incredible evidence tool that did not exist before. Although considered controversial by some as pre-placement warrant requirements are being fought in the courts, nobody can dispute the effectiveness of the technology.
Over the past 30 years, the United States dominated the space segment for global positioning. This will no longer be the case as the Russian Global Navigation Satellite System (GLONASS) was introduced to civilians in 2007. The Chinese and European Union are also working on their own systems further demonstrating the value GPS technology brings to all of us. Whether you own multiple vehicles needing a fleet tracking solution or are an individual with limited means, GPS tracking technology is an affordable luxury and is here to stay.

Explaining The 3 Elements Of GPS Tracking
GPS tracking relies on a constellation of satellites that form the Global Positioning System (GPS). These satellites, orbiting the Earth at an altitude of approximately 20,200 kilometers, continuously transmit signals containing information on their position and the precise time the signal was sent. The GPS consists of at least 24 operational satellites, ensuring that GPS receivers can access signals from multiple satellites simultaneously, enabling more accurate positioning.
5 Fun Facts On Satellites
- Minimum coverage: The GPS system requires a minimum of 24 operational satellites to ensure that at least four satellites are visible from any point on Earth, allowing accurate positioning.
- Orbits: GPS satellites orbit the Earth at an altitude of about 20,200 kilometers (12,550 miles) and complete two full orbits per day, ensuring global coverage.
- Atomic clocks: Each GPS satellite is equipped with multiple atomic clocks, which provide highly accurate time measurements. These time measurements are critical for determining precise locations.
- Signal transmission: GPS satellites continuously transmit radio signals containing their position and time data, which are then picked up by GPS receivers on Earth to calculate their exact location.
- Satellite replacement: GPS satellites have a lifespan of about 10 to 15 years. To maintain the system’s functionality, older satellites are replaced with newer, more advanced satellites that offer improved performance and features.
2. Ground Control
To maintain the accuracy and reliability of the GPS, the ground control component plays a crucial role. The ground control system consists of a global network of monitoring and control stations. These stations track the signals from GPS satellites, ensuring the satellites are functioning correctly and maintaining the precision of their orbits. The ground control stations also analyze satellite data and transmit any necessary corrections back to the satellites, which then incorporate these corrections into the signals they broadcast. This continuous process of monitoring and adjusting guarantees that the information provided to GPS receivers remains accurate and reliable.
5 Fun Facts On Ground Control Stations
- Essential role: Ground stations play a crucial role in maintaining the accuracy of the GPS system by monitoring satellite positions and providing necessary updates.
