In the 16th century, a young astronomer named Galileo from Pisa, Italy, formulated a new theory that proved the gravity of the sun. It was the first time that an object could be accurately measured and compared with the motion of a body. In this way, the movement of an object is said to be the same for all stars. This discovery was referred to as the "New Cosmic Theory." It was later developed by other scientists to predict the movement of the Earth and space.
After the launch of the Galileo satellites, the next major step is to begin the development of its functions. One of its major applications is global SAR. It is based on the existing Cospas-Sarsat system. The transponder installed on Galileo satellites transfers distress signals to regional rescue centers, which then initiates a rescue operation. Once the operation is completed, the system sends a response signal back to the user so that they know that help is on the way. This new service is considered a significant upgrade to the existing system.
The benefits of Galileo are many. It provides Europe with independence and sovereignty, as well as an array of other benefits. It also provides new services specific to the programme. Until Galileo, GNSS users relied on signals provided by non-civilians. This was no longer the case. Today, he remains under civilian control. With the help of Galileo, Europeans can use a GNSS system to find their way.
