Standford University - 13 October 2014

Today, the Global Positioning System (GPS) is deployed in over three billion devices across the world. This course will teach you the fundamentals of how GPS works and introduce you to the diverse range of uses of satellite navigation—in all aspects of our lives.

Through vivid online lectures and a set of "backyard experiments" enabled by the widespread availability of GPS-enabled smart phones and tablets, students will be able to connect online learning to real-­world experience. Even those who do not own laptop or desktop computers can take part; they will be able to view lectures and completing labs via mobile device only.

We hope students will enjoy the interactive nature of the course, while gaining knowledge that benefits their personal and professional lives. Please visit www.gps-lab.org for up-to-date details!
