The Global Positioning System (GPS) is the most significant recent advance in navigation and positioning technology. In the past, the stars were used for navigation. Today's world requires greater accuracy. The new constellation of artificial stars provided by the Global Positioning System serves this important need.
GPS a New Constellation was the companion exhibition to Planetarium show A Star to Steer Her By.
The content of GPS: a New Constellation and the broader history of navigation is explored in much more detail in the Time and Navigation exhibition on display at the Museum in Washington, DC.
