SOS Remote is a universal app for the iPhone*, iPod Touch*, and iPad that is used to control a Science On a Sphere® (SOS) system. SOS is a room sized, global display system that uses computers and video projectors to display planetary data onto a six-foot diameter sphere, analogous to an animated globe. SOS is used as an educational tool to help illustrate Earth System science to people of all ages in a way that is intuitive and captivating.
