SpaceStationAR is an augmented reality (AR) application that simulates the visibility of satellites in the night sky. With SpaceStationAR, you can easily spot the brilliant International Space Station, spectacular Starlink Trains, and various satellites at the forefront of space exploration with your own eyes! As your iPhone or iPad camera captures the scenery around you, SpaceStationAR overlays passes of the International Space Station, the Starlink Train (a group of Starlink satellites), and the Chinese Space Station onto the actual scenery. You can also use the app to find bright stars, galaxies, spacecrafts like Voyager 1 and Voyager 2, and even see the direction of major cities beyond the ground. SpaceStationAR also indicates the positions of geostationary satellites, making it a valuable tool for antenna installation. It can even forecast potential atmospheric re-entries of satellites. You can easily access satellite orbits on maps and celestial charts in addition to the AR views. The "Calendar" tab displays events like upcoming satellite passes and rocket launches within the next two weeks. You can choose a pass from the list and simulate it in AR. SpaceStationAR also comes with an Apple Watch app and a "Today" widget. If you have a compatible device, you can conveniently check a simplified satellite forecast list without needing to open the main app. List of Features * AR simulation of satellite passes overlaid on real landscapes * Real-time tracking of passing satellites (Exclusive to the paid version) * Display of stars, galaxies, black holes, planetary probes, satellites, and world cities in AR (Visibility can be customized by type) * Visualization of satellite passes on maps and celestial charts (Celestial chart feature is available in the paid version) * Presentation of satellite orbits and current locations on a global map * Calendar listing satellite passes within the next two weeks * Support for newly launched satellites * Turn on "Night Observation Mode" to switch AR and the celestial chart to a red-and-black color scheme, helping your eyes stay adapted to the dark (Night Observation Mode is available in the paid version) * Offline app usage * Forecasts potential atmospheric re-entries of satellites (currently in beta) * Satellite pass notifications: Set notification times from 15 minutes to 6 hours before the event for accurate alerts. (Please allow background location updates for precise notifications. Disabling this feature may lead to inaccurate notifications when traveling long distances with the app closed.) The LITE version of the app restricts AR mode display to 30 minutes before satellite passes and does not provide real-time AR functionality. Additionally, advertisements will be displayed at the bottom of the screen. http://itunes.apple.com/jp/app/torisat/id361194118?mt=8
