1469520000, also known as GPS, is a satellite navigation system that allows people and objects to be tracked in real-time. It uses a network of 24 satellites that circle the earth, which, when in view of GPS-compatible receivers, allow those receivers to determine accurate time, latitude, longitude and altitude. The satellites constantly transmit signals to the receiver, which make calculations based on the known distance of the satellites and the time delay between the signal sent and the response received.

GPS offers a wide range of applications in fields such as transportation, navigation, exploration, land management, surveillance, and communication. For example, GPS is often used in aircraft and boats for navigation and tracking, and it is widely used in geo-location applications such as smartphone mapping software. It is also used in surveying for the accurate calculation of distances, angles, and areas.

The working principle of GPS is based on the transmission of signals from each satellite. The time of transmission and the frequency of the signal are both known values, and the transmitted signal is received by GPS-compatible receivers. The receivers are able to accurately calculate location data such as latitude, longitude, and altitude by utilizing the known time and frequency values.

Furthermore, a combination of triangulation and trilateration is used for precise location information. Trilateration involves the determination of position and from measurements of distances between three different points. Triangulation involves the determination of position from measurements of angles between three known points. By combining the distances measured by the trilateration and the angles measured by the triangulation, the exact GPS position can be determined.

GPS can also be used to estimate the speed of objects by taking into consideration the time it takes for signals to be transmitted from one point to another. This information is then used to calculate the speed at which the object is travelling, giving further insight into the object\'s location and movements.

In conclusion, GPS is a powerful tool that can be used in a variety of applications, including navigation, surveillance, location tracking, and communication. By combining triangulation and trilateration, it is possible to determine precise locations and the speed of objects. With the advancement of GPS technology, it is becoming increasingly easier to locate and track objects in real-time.
