From time to time, I come across a little gem on the internet, in this case on YouTube. While not normally part of this blog, it seemed a good idea to share on this occasion. Consider the summary:
GPS receivers are a part of everyday life, you probably own several already and use them everyday, in your phone or in your car. Its really pretty amazing that you can find your position anywhere on Earth with just a small device you can fit in your pocket, but how does it actually work? In this talk we would like to guide you through the amazing technical journey that makes this possible and to open it up to the hacker community to explore.
What followed was a video with a clear presentation on the principles of GPS operation and how these technologies can be hacked (or not) to create new and innovative systems and products. While the presentation narration is a bit rough in spots, especially near the start, persist and you will be rewarded with many insights.
As always, your thoughts and suggestions are welcomed.
