Where Am I: Navigation and Satellites

How do we know where we are? What happens if you are completely lost in the middle of nowhere? Does technology provide tools for people who are lost during their travels? A person cannot usually determine an accurate position just by looking out a window in the middle of the ocean or vast area of land, particularly if it has not been charted before. In this lesson, students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. Also, students learn how these technologies can help people determine their positions or the location of someone else.
