Constellations of the Earth app for iPhone and iPad

This application “Constellations of the Earth” is a tool for smartphones to help you visually understand the Art project “Constellations of the Earth” that started in 2013. “Constellations of the Earth” uses the Japanese land observation technology satellite “DAICHI-2” (ALOS-2) and the handmade radio wave reflector “Corner Reflector” (CR), and is several kilometers to several tens of kilometers above the ground. This is an Art project that creates a new “constellation” in a large area. This application displays the location of the activity so far, the orbit of the artificial satellite on the day, and the ground observation area by radio waves, and can switch the viewpoints overlooking the entire earth, artificial satellites, and radio reflectors. I can do it. In addition, it has a function to link the direction of the digital compass of the smartphone and the direction of the radio wave reflector on the screen, and a function to adjust the speed at which the artificial satellite travels in space by operating a sludge. Helps you understand.
