New project - Animation of Starlink satellites

General
1

I’m hoping to create a web page that will show the positions of the Starlink satellite sin the sky.

General idea is as follows:

Starlink visulisation project.

  1. Web page to call recent GP elements (one line csv) file from satsig server. ( Was 2 line elements )
    e.g https://www.satsig.net/satellite/tls-archive/gp-starlink-2026-08-15.csv

  2. Process this to generate, for each satellite, starting positions (Aries longitude, latitude, height) at GP element Epoch.

  3. For current time and each satellite work out positions now (Greenwich longitude, latitude, height).

  4. From now on various options about display.

    on flat lat/long grid show satellite positions.

    draw coverage capability based on an elevation angle.

    centre the map on selected (eg. user) location.

    Animate to show satellite movement.

5 Option to choose different GP element set for different constellation.

No progress so far.

Also no new member of this new forum. Maybe I’ve got it wrong but trying to get new members.
