The application itself will allow you to setup your phone to take pictures at a specific interval as well as send out SMS messages at specific intervals with the phones current location, speed, and distance.
After tracks/flights are recorded SpaceTracker can export the GPS data to a KML file to display the flight path in Google Earth.
SpaceTracker is useful for not just High Altitude Balloon Experiments but can be used for sending your location while driving/running/biking to keep loved ones in the loop. Really the possible uses for the application are endless.
