Calculating position from raw GPS data (2017)
We are all familiar with GPS (Global Positioning System) and its myriad applications. From getting directions using Google maps to hailing a ride using a ride sharing app, countless individuals and businesses rely on accurate position estimation using GPS.
The wikipedia article referenced above also provides an interesting history of the origins of the GPS system dating back to Sputnik, the first man made satellite launched in space. After reading this post, a casual reader should have a better understanding of GPS, so the next time they use Google maps on their phone, they are aware of the amazing technical infrastructure that makes positioning and navigation applications possible. I considered writing my own RTCM decoder, but then found an excellent Matlab library called goGPS (http://www.gogps-project.org/about/) that provides many useful routines to read and process GPS data.
