And, the answer for the the question is :
Explanation:
The Navy Transit 1B, which was put into orbit on April 13, 1960, was the first navigational satellite and a precursor to the Global Positioning System, or GPS. The Navy’s Polaris missile, which is launched from submarines, utilised the technology to facilitate navigation. The whole public can obtain GPS technology today.
In 1960, the US Navy launched Transit, a satellite-based navigation system that was the precursor of modern GPS technology. Transit was the world’s first operational satellite navigation system and was a significant technological advancement that had a profound impact on navigation and positioning.
Transit was developed by the Johns Hopkins Applied Physics Laboratory and was initially designed for use by the US Navy’s submarine fleet. The system used a constellation of satellites in low Earth orbit to provide accurate positioning information to submarines. Transit worked by measuring the Doppler shift of radio signals transmitted by the satellites. By analyzing the frequency shift of the signals, the system could determine the position of the receiver.
Transit was a significant improvement over previous navigation systems, which relied on celestial navigation and dead reckoning. These methods were time-consuming and required a high degree of skill and accuracy. Transit, on the other hand, provided accurate positioning information in real-time, which allowed for faster and more efficient navigation.
Transit was also used for civilian applications, such as surveying and mapping. The system was particularly useful for offshore oil exploration, where accurate positioning was critical. Transit was also used by the scientific community for geodetic studies and by the US Coast Guard for search and rescue operations.
Transit had some limitations. The system was only accurate to within a few hundred meters, which was not precise enough for some applications. Transit was also susceptible to interference from the ionosphere, which could cause errors in the positioning data.
In the 1980s, the US government began developing the Global Positioning System (GPS), which was based on the same principles as Transit but with significant improvements in accuracy and reliability. GPS uses a constellation of satellites in medium Earth orbit to provide accurate positioning information to users all over the world. The system is now used in a wide range of applications, from aviation and maritime navigation to personal navigation devices and location-based services.
Transit was a groundbreaking technology that paved the way for modern GPS systems. The system demonstrated the potential of satellite-based navigation and positioning and provided a foundation for future developments in the field. Today, GPS technology is an integral part of our daily lives, and we rely on it for everything from finding our way around town to navigating the globe.
