• AMSAT Online Satellite Pass Predictions. (Web-based)

• N2YO provides real time tracking and pass predictions with orbital paths and footprints overlaid on Google Maps. It features an alerting system that automatically notifies users via SMS and/or email before International Space Station crosses the local sky. The N2YO.com system powers ESA's, Space.com's and many other's satellite tracking web pages. (Web-based)

• CalSky a service offered by Arnold Barmettler for astronomers to plan their observing sessions. Features a calendar (and/or email notifications) generated for your location including information on aurora, comets, tides, solar and lunar eclipses, planets, bright satellite passes (ISS, HST, etc.), occultations, transits, Iridium flares, and decaying satellites that may be visible. (Web-based)

• https://satellites.calum.org/ Free REST API for single and multiple satellite predictions, focussing mainly on Amateur Radio satellites. Offered as a "best effort" resource. (Web-based)

• Spectator, allows real-time tracking and overpass prediction for Earth Observation satellites. It also connects to data APIs, allowing users to get latest images from tracked satellites. (Web-based)

• Where the ISS at? provides real time tracking and push notifications (via email) for ISS passes over your location. REST API available as well. (Web-based)

• ISS onlne ISS Live webcam. ISS passes over your location. Photo from ISS on map. ISS tracker. Current ISS Crew. (Web-based)

• tracksat.space, free web application for tracking satellites orbiting Earth. Allows to check passes over chosen locations, predict satellites' future positions and set up custom browser notifications. Users can create their personal dashboards to display data for multiple satellites and ground stations. (Web-based)

• GoSatWatch from GoSoftWorks, supports multiple viewing sites (home, vacation spot, etc.), no internet connection required (one data is loaded and periodically updated). View satellite position on world map or a simple polar chart showing the path the satellite will take across your sky.
  
  (iOS) (Mobile devices)

• ISS Visibility, interface to Heavens-Above, predictions up to 30 days out, ground tracks, star chart with path shown.
  
  (iOS) (Mobile devices)

  (iOS) (Mobile devices)

• "Star Walk: Constellation Finder" from Vito Technology Inc shows both Iridium flares and ISS passes.
  
  (iOS) (Mobile devices)

• Satellite Tracker - (ProSat) Displays satellite paths 7 days in advance and operates offline until additional days are needed. Compass view of paths as well as 3D earth view. Allows user to input and store satellite radio frequencies while accounting for live doppler shift.
  
  (iOS) (Mobile devices)

• ISS onLive, app with live cameras of ISS, realtime tracking position and visible passes prediction. It also predicts sunrises, sunsets and daytime passes.
  
  (Android) (Mobile devices)

• Satellite AR, by Analytical Graphics augmented reality view of the sky for currently visible satellites only. Includes modes for ISS and bright objects as well as modes which include the thousands of all known satellites.
  
  (Android) (Mobile devices)

• Satellite Passes, supports world map view, augmented reality view, satellite footprint, simulation mode and notifications.
  
  (Android) (Mobile devices)

• Heavens Above has an Android app with functionalities similar to the website.
  
  (Android) (Mobile devices)

• ISS Detector – shows ISS position and Iridium flares.
  
  (Android) (Mobile devices)

• Look4Sat – predicts satellite passes from a two-line element set database, including a polar view function with satellite footprints.
  
  (Android) (Mobile devices)

• Spymesat, by Orbit Logic, a mobile app for iOS and Android, computes pass predictions for any selected location for available commercial and unclassified government high-resolution imaging satellites and provides real-time notifications and dynamic real-time imaging resolution and satellite position information and maps during predicted passes. SpyMeSat also includes the ability to download recent high-resolution satellite images for the user-selected location, or task selected imaging satellites to take a new image.
  
  (Cross-platform) (Mobile devices)

• Astro::satpass Perl library by Tom Wyant, calculates star, Sun, and Moon positions as well as satellite pass predictions. Interfaces with Celestrak or Space Track. (Software libraries)

• OreKit Java library for low-level space dynamics library. (Software libraries)

• Celestrak provided by Dr. T.S. Kelso, includes visible objects, openly available (Raw orbital data)

• SpaceTrack maintained by the United States Strategic Command provides orbital information on unclassified satellites requires an account but is available for educational and hobbyist use as well as military, government and spacecraft and payload owners. (Raw orbital data)
