GPS achieves its high precision through the use of a network of satellites that transmit signals to receivers on the ground. By calculating the time delay between when the signal is sent and received, the receiver can determine its exact position. Advanced algorithms correct for factors like atmospheric conditions, further enhancing accuracy.
