Updates (Last: 15th October 2025)
Planet earth imaging /vis/constellation/planet group now shows up. As does Tianqi /vis/constellation/tianqi . Rotated starlink rx/tx ground footprints to be fixed to reference frame of satellite.
Dedicated page for re-entries recent and upcoming: /re-entries or menu item Functions .. Re-Entries .
Added export the current set of satellites in the visualizer, as a CSV file. Added an frienly explanation of the optimal satellite-train viewing opportunities.
More performance for slower devices and less data transfer for slower internet connections.
Recent re-entries are now held at their predicted re-entry position and their orbit track, that shows when the satellite is clicked, now shows in red, and ends there. Satellite-train visibility calculator now revreals if the train is sunlit from the correct direction to optimize visibility.
Satellite train visibility in your sky are now available at /vis/trains and clicking on the telescope at the start of any row loads the camera simulation page with parameters set to simululate a 10x speed video showing the pass. There are many satellite trains right now.
Celestrak TLEs are now incorporated if space-track is slow. In /space-track-status they are marked as C*. As a result the position information and satellite count has caught up to the recent launches and there are a lot of starlink trains visible. (Go to the visualizer and select the TRAINS button from the row of buttons. If you don't see this button, look in /settings and configure your control buttons to include it). Some tweaks made to label sizing, and the CPU saver function if the clock is paused, or if there is no interaction. In /settings you can enable an aggressive CPU saver option that halts rendering but still runs the clock, unless page events are seen. A re-entering satellite in POV mode now includes a cute glow effect. If you encounter a bug please use the /feedback link! Few people bother to report anything anymore. If I do not know something is broken it won't be fixed.
Cosmetic face lift: The tool /satellite-photobomb now supports time-lapse video simulation. Not so useful for fast moving satellites but fun to rotate the galaxy. Label rendering is improved. The clock now turns red for time before now, and blue for time after now. The sun now sets and rises in yellow in standing view. The land mesh has lighting and water looks better. When pausing time the cpu use drops to zero if you cease interacting. GEO interference calc tool will now offer a text, printable, table.
LEO Internet satellites now, if selected, render a conservative service-footprnt including the clarke belt exclusion shadow. Improved touch/click interface you can now manipulate the camera by dragging satellites around rather than only ever rotating the earth - just click or touch a satellite and move it. Hovering (mouse) now auto-shows the label that would show anyway with a close camera. Numerous little bugs squashed.
A long press on the visualizer toggles zero-decoration mode. Just the globe and the universe.
Now you can load any combination of Satellites into the visualizer with a load filter panel: Functions.. Sim.. Load...
Starlink Timeline - Launches table now identifies the recent launches that are still lacking space-track position data. Space-track re-entry information (TIPS) and satellite trains are new globe information overlays that are evolving.
The tool /satellite-photobomb will now export for download a generated mp4 video file (at three optional speeds) or a timestamped image of satellite trails, as per your shot set up. You can finally change the clock back to any date and if we store historical TLEs, get an accurate visualization at that time. Bugs selecting and un-selecting satellites have been fixed. Daily unique visitors are now up over 20,000.
The table of transits at /vis/sky-transits for a given satellite (default is ISS but the function is available for any satellite) now links directly to the /satellite-photobomb calculatior via a telescope icon where all the parameters are set up to "see" the transit. This is a cool cross-reference between the calculation of a transit and the simulator visuals. Meanwhile, space-track data publishing appears to be stuttering, again and TIPs for re-entries have ceased, again, after a short burst. Your past searches are now remembered. Lots of minor bug fixes.
Restored more of the classic IOS app functionality. If you are interested in satellite pollution of astro photography or reconstruction of satellite movements for a given camera location, direction and focal length, then this tool might be of interest: /satellite-photobomb. There is still functionality to finish, however.
Added a page to keep track on space-track.org API feeds - it is at /space-track-status. Restored the notification window that identifies changes in constellation since last visit. /vis/constellation/starlink/availability : Starlink Availability menu option is now a toggle and a note appears to explain that availability is derived from IP BGP exploration, so might include soon-to-be-available countries as well
Revised the Functions > Calculators > TLE Calculator tool for example, added a slider for orbit plots, and warn when loading just decayed or imminently-decaying satellite TLE data. Verified again that space-track.org is still failing to publish satellite re-entry predictions. Added a recent-altitude graph button to the Altitude History panel of a satellite. Revised the Constellation navigation drop-down menu. Added a calibration-to-north option for AR mode because web pages are not allowed to receive accurate compass data on IOS or Android. Fixed many small bugs. Added a last-site-visit memory that informs a "constellation change since last visit" info display. Read that google is declaring the open web to be dying because they stole all revenue sources by herculean efforts to stop their 90% market share in search from clicking on from their ad-strewn search results.
The old IOS app now uses the new visualization. There are some loose ends for this IOS app to clean up to fully reinstate its original functionality, thanks for your patience if you paid for it in the past. Did you know you on IPhone or Androd you can "install to home screen" this whole website and get a full screen experience?
Built this new page and accordions. "older updates" exclusively refer to the "classic" version of satellitemap.space.
Show older updates...
Changed the definition of 'parked' vs 'in service' to a lower altitude break of 445km thus the in-service graph jumped and the yellow in-active line dropped
This page is old and refers to changes made to the old visualization it is here because I don't know why also it has the Privacy Policy and other sections
Another 27 Kuiper satellites are catalogued just in time for the very frugal and not at all out of touch Bezos wedding
Added Globalstar and Iridium networks. Will work on some improvements to the display of the non-starlink networks next
A better close conjunctions algorithm runs faster and finds all conjunctions (previous one did not find all). Added loading notification when starting up globe display.
When clicking on a satellite, associated satellites on same orbit are more correctly picked out. Inclination is added as an attribute
Kuiper - the new Amazon constellation - is now in tracking
When the new Amazon constellation appears in the tracking, I will add it
Updated the One Web constellation and the GPS satellites. Added a "no label" option so satellites can be shown as just dots when fully zoomed in. Fixed up the much mis-used feedback facility (that page where you submit a request or a bug etc). Now I use deepseek to filter out the bot generated form-submission rubbish so I can actually read actual feedback instead of ignoring it all by default.
For some time functionality additions to satellitemap.space have ceased as it works ok as it stands. With the number of starlink satellites up now there is little use for the old functions of "having starlink", "wanting starlink", or "ordering starlink" and the functions to display availability by hexagonal cells on the globe are way out of date. While there is no additional function planned and the google play app has been removed due to onerous google play store development hurdles and red-tape, the data is still being updated continuously from public sources and the orbits are still being correctly calculated and the IOS app Augmented display of satellites should still be correct. Since Twitter has turned into a cesspool and the CEO is a total prick, integration with twitter was ceased so notifications of satellite re-entries, new launches, very close satellite to satellite passes and so on are published nowhere. Running the site costs money in hosting fees and occasional work and it represents many hours of programming before this time when AI coding supposedly does everything for you. There are no ads or other sponsors even though monetisation companies are ready to ruin the page with pop-ups pop-unders and so on. That's the 2025 update!
Updated the conjunctions page today. Some more site updates are in the pipeline.
All the recent altitude history graphs and batching of satellites per launch were buggered up due to errors in automated data retrieval -- this was untangled and now the data looks ok again and hopefully will stay that way.
Automation of tweeting for following events: additional launches scheduled, additional catalogued satellites from recent launches, close conjunctions to ISS or CSS
Added launches pages for starlink launches which lead to individual orbit insertion graphs.
The three approximate Italian ground station locations have been added. Without online copies of any official paperwork and approvals the lat/long or current operational status is uncertain
Not a lot to report. During a pause in starlink launches, quite a number of re-entries are happening. Judging by misdirected emails a large number of customers are waiting in limbo with little to no information from Starlink on their order progress. If you follow our twitter, the monday movie is getting tweaked slightly.
