How to use

Updates (latest first)

* 14th June - added two more launches

* 21st May - added two more launches, fixed bug where ground stations were not being added as they are found, (see Europe for new ground stations), show starlink names with sufficient zoom. Added a close X to altitude history window.

* 6th May - updated the How To Use section below and reformatted the preferences modal slightly

* 16th April - added March 25th oneweb launch, and starlink launch 25 (24 officially)

* 14th April - launch 23 and 24 (22 and 23 using wikipedia numbering) have norad IDs now

* 31st March - nearby satellites to your home lat long over the horizon that are sunlit are now shown in yellow. If your location is after sunset or before dawn you may be able to locate these visually by elevation and azimuth, depending on reflectivity and other factors. Thanks to @laurenlaufman for this idea.
Launch 22 (official launch 21 / March 11th) is added. 14th and 24th launch sats are not yet in Norad.

* 30th March - Data dumped for visibility now includes all satellites over 25 degree elevation plus a new column for whether or not the red line is drawn (cone of receiver). You can now do your own analysis by filtering for azimuth and elevation to determine number of satellites in view assuming a certain dish orientation

* 28th March - Folder icon downloads visibility data as a CSV if browser is left viewing 'home'. (work in progress). An hour of data is roughly representative of theoretical connection status at your latitude but with many uncertainties.

* 21st March - fixed bug where green home dot did not appear. Zooming in now gives elevation and azimuth to "in range" satellites. State boundaries now plotted.


How to use

Most preferences can be set (persistently stored) using the cog (settings) link at the top. You can increase performance by turning off rings, turning off ground station dots and filtering for active satellites.

Preferences can filter by launch number or numbers. Enter the list of launches with commas for example 24,25 would display only the satellites from that launch

Day/Night refers to coloring the satellites according to whether they are over land after sunset or after sunrise

Rings refers to very approximate area of usability. Of course the actual direction the reception dish determins actual visibility

Enter your home address in lat/long form (note the numbers must be negative f you need to enter West or South numbers) to enable default display of your immediate satellites and view count

Mouse: click hold and drag to move globe, zoom in with scroll wheel or two finger touch pad move. Zoom for more detail.

Mobile: use normal touch operations to move and zoom/unzoom globe

The folder icon accumulates data on visibility of satellites second by second. Click it to download the file for your own amusement and processing for example to determine your own metric on visibility over an hour

Map is live from latest observational data from space track dot org.

You can click satellites, or click ground stations for further information

This is not a resource affiliated in any way with SpaceX, Starlink, Tesla, Elon etc etc nor is it any official service. The data comes from public tracking data published at space-track.org. The calculations and visualization are best effort and you should not use it as authoritative.


You have permission to use screenshots in articles or other media however if you do so, please include either a clickable link or if that is not possible, clearly indicate the source of the picture video or other mention as (satellitemap.space). Feel free to ask questions via DMs on twitter above I might even be able to answer some of them.
