Decoding GPS: Trilateration and Accuracy

This chapter explores the mechanics of GPS technology, focusing on trilateration and how it calculates locations using pseudo-random codes and signal transmission times. The speakers engage in a lighthearted discussion about the challenges of accurate positioning in GPS, including the effects of obstacles and the concept of differential GPS. Through humor and illustrative analogies, they explain the significance of overlapping circles and spheres in determining precise coordinates in three-dimensional space.
