About SpaceTrackr

This site is an online satellite tracking system that allows you to view in real time positions of various space objects in Earth's orbit, such as the International Space Station (ISS), the Space Shuttle, GPS and Iridium satellite constellations, and over 5000 spacecraft and debris. You can also view visibility footprints and tracks of space objects predicted using data collected by NORAD and usually updated on a daily basis. The precision of satellite footprint and track calculation can be customized to your needs.

Many powerful and interesting features are planned; if you have your own ideas, please use the Feedback tab to submit them!

Development roadmap

Optimizations

1. Find a faster GeoIP service
2. Use Ewindow extension (http://econym.org.uk/gmap/ewindows.htm)
3. Enable predict calculations on the server side
4. Radically improve track/footprint calculations
5. Make my own version of day/night overlay

Uninterrupted workflow fixes

6. Download and apply new TLEs and spacecraft info from time to time
7. Manage updates to satellite and section lists
8. Process decays of objects being tracked

Special sauce

9. Ajax & HTML APIs for tracking a single satellite by its id in an iframe
10. Set icons, trajectory and footprint colors for individual satellites
11. Personal OpenID accounts
12. Predict tools & visualizations
13. RSS with launch/decay announcements
14. Space exploration wiki
15. Look out of this satellite's window
16. Planetarium with satellites as seen from the home location
17. Live video feeds of launches, video archives, launch sequence logs and history
18. Live telescope webcam transmissions

Completed

19. Mirror NSSDC content
20. QD prototype: put together GMaps API v.2, a GeoIP service and PredictLib
21. QD Tool for tracking a single satellite by its id in an iframe
22. PredictLib is very inaccurate. Find out why and fix..
