Ivan Getting was an American physicist who was responsible for developing the technology that allowed GPS to accurately determine an object's precise location. He proposed a system that used satellites to provide location data for military purposes and worked as a consultant to the Department of Defense on the project.

Bradford Parkinson, another American physicist, was the chief architect and program director of the GPS project. He was responsible for the system architecture development and played a key role in advocating for the commercialization of GPS technology, making it available to the general public.

Both Getting and Parkinson played an instrumental role in creating and implementing GPS technology, earning them the nickname "The Fathers of GPS."

Contributions from Others

While Getting and Parkinson are credited with inventing GPS, many other individuals made significant contributions to the development of the system. Roger L. Easton, Jr, an American physicist, was also critical to the creation of GPS technology. He was the principal inventor and designer of the US Navy's Navigation Satellite System (TRANSIT), which served as the precursor to the GPS system. Easton's research on satellite navigation paved the way for GPS technology as we know it today.

Another notable figure in the development of GPS was Gladys West, an American mathematician and computer programmer who worked on the project early in her career. West played a crucial role in developing the mathematical models that accurately determined satellite positions and orbits. Her work laid the foundation for GPS technology and its widespread adoption.

In conclusion, while Ivan Getting and Bradford Parkinson are often credited with inventing GPS technology, many other individuals contributed to its development, making it the revolutionary technology it is today.

Who Invented GPS?

A commonly asked question among technology and history enthusiasts is, who invented GPS? GPS or Global Positioning System is a technological marvel that has transformed the way we navigate our world. Through GPS, we can accurately determine our position, plan routes, and navigate through otherwise challenging terrain with ease.

While GPS technology has come a long way in the past few decades, many people are still unaware of who invented the technology. The answer to this question may surprise you, as GPS technology is the result of collaborative efforts by several individuals and organizations.

Overview of GPS Technology

GPS technology works by a network of satellites orbiting the Earth. These satellites transmit signals to GPS receivers on the ground, which use those signals to determine the user's location.

There are currently 24 GPS satellites orbiting our planet and they are operated by the United States government. These satellites are designed to transmit signals that can be picked up by GPS receivers on the ground. The data transmitted by these satellites is used by the receivers to determine a user's location on the planet accurately.


The process by which GPS determines a user's location is called trilateration.

When a GPS receiver receives a signal from a satellite, it uses the time it took for the signal to reach the receiver to determine the distance between it and the satellite. This process is called measuring the signal's "time of flight."

GPS receivers must receive signals from at least three satellites to calculate a user's position accurately. This is because a single satellite can only determine a user's position on a line from itself. However, with three or more satellites, the receiver can pinpoint the user's location in three-dimensional space.

Accuracy and Limitations

While GPS is generally very accurate, there are some limitations to the technology.

One limitation is that GPS signals can be weak or unavailable when there are obstacles such as tall buildings or mountains that block the signals. In addition, GPS signals can be jammed or interfered with by other electronic devices, making it challenging to determine the user's location.

To counter these limitations, new technologies such as GPS augmentation systems have emerged. These systems use additional satellites and ground-based transmitters to enhance the accuracy and reliability of GPS data. They are particularly useful in urban areas where it may be challenging to receive a clear GPS signal.

The Collaborative Effort Behind GPS Technology

While there is no single individual credited with inventing GPS, several notable individuals and organizations contributed to the technology's development.

In 1973, the US Department of Defense began working on a system for global navigation. In the following years, this project led to the creation of the first GPS satellite, named Navigation Technology Satellite 2 (NTS-2), which was launched in 1977.

A few years later, in the 1980s, the first GPS receiver was invented. The receiver could determine a user's location to within a few meters. This sparked interest in the technology, and more companies and individuals began developing GPS devices for civilian use.

The 1990s marked a significant milestone for GPS technology when the US government allowed civilians to access the GPS signals for navigation. The availability of GPS data to the public triggered the development of more sophisticated GPS devices, including those used in cars and smartphones today.

Today, GPS is a ubiquitous technology that has transformed the way we navigate our world. Whether we are driving, hiking, or exploring new cities, GPS helps us get where we need to go safely and conveniently.

Wrapping Up

In conclusion, GPS technology is the result of collaborative efforts by several individuals and organizations. While there is no single individual credited with inventing GPS, the US Department of Defense, along with many other parties, contributed to its development. Today, GPS has revolutionized the way we navigate the world, and its applications are endless.

Early Applications of GPS

GPS technology was first developed by the United States Department of Defense for military purposes. In the 1980s, the technology became available for civilian use. It didn't take long for people to realize the potential of GPS for navigation. Companies like Garmin and TomTom began producing GPS devices for cars, making it easier for drivers to find their way to new destinations.GPS also became widely used in surveying equipment. In the past, surveyors relied on manual calculations to determine the location of landmarks and boundaries. GPS technology made their jobs easier and more accurate, as the system could provide precise coordinates for any given location.

Advancements in GPS Accuracy

As technology advanced, so did the capabilities of GPS. In 2000, the introduction of selective availability (SA) was turned off, which made GPS accuracy improve significantly. In the early days of GPS tracking, it was common to see inaccuracies of up to 100 meters, but with the SA turned off, GPS accuracy improved to just a few meters.The introduction of new satellites has also improved GPS accuracy. The newer satellites, called GPS III, are more powerful and provide a stronger signal, making it easier to track and locate objects.Another development in GPS technology is the use of augmented reality. Some GPS devices now incorporate cameras and sensors to show users real-time information about their surroundings. For example, they can show street names and directions on the actual road in front of the user.
