【實用工具app】Space Station (ISS)|最夯免費app

ISS is part of the Sat series of applications (ISS, HamSat and ProSat) and is a visualization/utility application that allows you to see the location of the International Space Station and other associated satellites (Soyuz, Progress, PSSC...) in realtime over the Earth (up to six satellites may be tracked simultaneously). NOTE: NORAD only updates their elements once a day so rendezvous operations will be accurate pre-chase but until NORAD updates the elements for the rendezvous vehicle's state (within 24hrs) the position will look incorrect post dock.You can see the Earth rendered either as a 3D globe or a 2D map using photo realistic texture maps for the Earth model. The orientation of the map is easily changed by a simple rotation of the device from portrait (3D) to landscape (2D). In either orientation you can zoom in and out as well as pan using the touch screen. Controls are given to allow you to select: the texture maps used, whether shading is performed, whether to draw political boundaries and if a lat/lon grid should be presented. In addition, the application can calculate the rise/set times of the primary satellite, Sun and Moon for your specified location. In the case of the satellite calculations, you can further specify whether the overflight times should take into account optimal ground viewing characteristics (meaning the satellite is lit, the ground is dark and the max elevation is greater than 10 degrees)If you want access to more satellites then please check out either HamSat (satellites specific to Amateur Radio operators) or ProSat (includes access to 700+ satellites)-- Feedback Answers/Notes ---The current application can compute both overflight (horizon to horizon) and viewing opportunities (visible to the naked eye from the ground meaning the ground has to be dark and the satellite has to be lit)-The application does not go to your default location on startup but rather the location of the primary satellite being tracked. This is by design as the application was written for satellite controllers who need to know the vehicle's current position.Thanks for the feedback and keep it coming,-Craig
