2. What is GPS?
Global Positioning Program (GPS) was developed by the U.S. Department of Defense for the navigation needs of the military.
Since then, it has become an asset for civilian applications & industries around the globe.
GPS employs 24 spacecrafts, placed in 6 orbit planes. GPS receivers use triangulation of the GPS satellites' navigational signals to determine their location. The full constellation was completed on March 9th, 1994.

3. GPS for cars & cell phones
When following directions, you can use street view to see what each step/ stop will look like – no more getting lost!
Google Maps Navigation for Android 2.0

4. How does NASA’s satellite tracking work?
Fun fact: there are over 8,000 artificial objects orbiting Earth—over 2,500 of these are satellites (the rest are orbital debris)
There are two types of JAVA applets in which you can view satellites: J-track & J-pass
This technology allows for live 3D snapshots

5. How does Google Earth get their images?
They used to use Digital Globe’s QuickBird
They are now using the new GeoEye

Google is actively replacing this base imagery with higher resolution
