Geolocation involves accurately determining the precise geographic location on Earth that corresponds to a signal received from a satellite.

Satellites in various orbits transmit signals to Earth, which are then received by ground-based stations or user devices. Geolocation relies on multiple reception points, such as GPS receivers or ground-based tracking stations, strategically positioned across the globe. These receivers collect the transmitted signals from the satellite, and through a process of triangulation or multilateration, the exact position of the satellite relative to the receiving stations is calculated.

By analysing the time it takes for the signal to travel from the satellite to multiple receivers, the distance between the satellite and each receiver can be determined. Combining this distance information with the known positions of the receivers allows for precise calculations to pinpoint the satellite’s location in three-dimensional space. The process involves intricate mathematical algorithms and advanced signal processing techniques to achieve high levels of accuracy.
