# Understanding GPS: Position Calculation and Applications

Calculating Position from Raw GPS Data 🔗

The text explains the process of calculating position from raw GPS data. It covers the various coordinate systems used to express position, the basic principle of triangulation used by GPS to calculate position, and the application of GPS to calculate user position from satellite measurements. The post also discusses the ownership of GPS, the implementation of GPS-like systems by other countries, and the history of the origins of the GPS system. The author also presents the Matlab code for implementing various ideas discussed in the post and describes the experimental setup used to collect raw GPS data, as well as the analysis of the results.
