👉 Global Positioning System (GPS) math is a complex mathematical framework that enables precise location determination by satellites orbiting Earth. At its core, GPS relies on trilateration, a method that calculates a position based on the time it takes for signals to travel from multiple satellites to a receiver. Each satellite transmits its position and the current time, which the receiver uses to compute the distance (pseudorange) from each satellite. By solving a set of nonlinear equations simultaneously, the receiver triangulates its exact location in three dimensions (latitude, longitude, and altitude). This process involves complex algorithms to account for various factors, including satellite clock errors, atmospheric delays, and the receiver's own motion, ensuring accuracy within centimeters.
