Sputnik! vs Satellite Tracker

Sputnik! is an easy to use tool for predicting when the International Space Station will pass by your location or when a bright satellite will be visible in the skies above. Sputnik! features: - Predictions of satellite and ISS sightings accurate to the second. - Detection of Starlink satellite trains. - Second by second countdown to the satellite sighting. - Set reminders of upcoming satellite sightings. - Displays compass direction and elevation for your device to easily find the part of the sky where the sighting will occur (requires capable device). - Rotate your device to landscape orientation to show exactly where the satellite will pass in the night sky. - Share sightings via Twitter, Facebook, Mail, Messages and others. - Automatic download of up to date satellite orbital data. - Offline calculations, no need to be connected to the internet once orbital data has been downloaded. - Input your location automatically by GPS, select from a map or enter coordinates manually. - Save your favorite places for easy access. - Audio cues for the last seconds before the satellite passes by. Sputnik! on Apple Watch: - Easily find the next and last sighting at your current location. * Sputnik! is ad-supported *

Satellite Tracker is the follow on to our award winning HamSat series of applications. Satellite Tracker merges all the features of the iPhone and iPad versions providing you a single application that seamlessly optimizes the screen to the device you’re running it on (check out the various iPhone and iPad screen shots). The application will calculate the rise/set times and associated azimuth and elevation for the selected satellite, Sun or Moon given either the user entered or network retrieved location. There are two modes for satellite rise/set calculations. The first is for those folks wanting to know all overflights for a given location (like Ham radio operators) while the second mode computes only those passes where the satellite would be visible to a ground observer. In the ground observer mode, the calculations not only take into account that the ground is dark but also that the satellite is in sunlight (it even takes into account if the satellite becomes lit or unlit during the pass) In addition, 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. There are more than a dozen controls provided to allow you to customize how the application works to meet your specific needs (type of Earth texture used, location, type of overflight calculated…) Finally, the application is now free to download and provides full functionality for tracking, viewing and communicating with the International Space Station (what was the capability of the ISS family of paid apps). The following subscriptions are available for tracking and communicating with a larger set of satellites: -HamSat (Annual and Monthly): Provides access to the NORAD and AMSAT two line element sets which cover all amateur related satellites. -ProSat (Annual and Monthly): Provides access to thousands of satellites grouped into the following categories (from www.celestrak.com): -100 (or so) Brightest -Last 30 Day’s Launches (or so) -Amateur Ham Radio Satellites -CubeSats -Disaster Monitoring -Earth Resources -Education -Engineering -Geodetic -Geostationary -GOES -GPS Operational -Intelsat -Iridium -Molniya -NOAA -Orbcomm -Search & Rescue (SARSAT) -Space & Earth Science -Space Station -Weather To get a feel for the apps, please checkout the iPad quickstart video (http://www.youtube.com/watch?v=tiHCGxV0WM8) and associated user’s guide (http://www.vosworx.com/wp-content/uploads/2017/05/SatSeriesHD.pdf) or the iPhone quickstart video (http://www.youtube.com/watch?v=iuPccQI9oSg) and it’s user’s guide (http://www.vosworx.com/wp-content/uploads/2017/05/SatSeries.pdf).
