The Astro Wave is an international Wave Road high above the earth that connects the EM-waves of different counties and cities in the MegaMan Star Force series. MegaMan can use the Astro Wave road to quickly move between different areas. The Astro Wave was added in the 3rd game. The Astro Wave is in space, which appears to be an upgraded version of the Sky Wave, which appears in the 2nd game.
