I recently took my first dive into Celestrak which provides coordinates (TLE's) for all sorts of satellites. Fascinating project I want to learn more about how changes in trajectory are executed by different operators and are communicated more broadly.

Here's some of their Starlink data: https://celestrak.org/NORAD/elements/table.php?GROUP=starlin...

More on the TLE format from wikipedia: https://en.wikipedia.org/wiki/Two-line_element_set

There's a nice blog post from Planet about their approach: https://www.planet.com/pulse/keeping-space-clean-responsible...
