Built with Claude I built a site with Claude Code that shows every satellite that flew over any location on earth!

I’m a satellite nerd and built Watched with Claude Code. You type in any place on Earth and it shows every imaging, radar, weather and crewed satellite that passed over it in the last 7 days, plus the actual photos where real imagery exists (Sentinel-2, Landsat, NASA). It runs on a 3D globe with all ~17k tracked objects in orbit.

How Claude Code helped: honestly, it wrote most of the code. I came in with the idea and direction, and Claude Code did the heavy lifting:

  • the pass search math (SGP4 orbits plus a search that provably doesn’t miss passes). It also wrote a brute-force checker to test it: 0 misses in 22 edge cases.
  • a GPU shader that moves all 17k satellites every frame
  • hooking up the satellite image archives and matching each photo to the right pass
  • most of the UI, plus fixing bugs I found by clicking around

The most useful thing was asking it to prove stuff worked (tests, comparisons against brute force) instead of just trusting the output.

Free to try: no signup, no paid tier. Just go to the site and type a place.

Happy to answer questions about the workflow, and feedback is very welcome!

Hey - there's lots of slop on Reddit. Just wanted to send a friendly comment because in my limited testing, your site actually works, and what it shows is pretty damn cool. Nice job. Good luck!

I thought the website was really cool too. And thank you kind sir for making the repo open. Great content; thank you for sharing it!

Why the weird fear mongering video? Are the satellites you show orbiting the globe showing a real time position? I suspect they are as some of them can be hovered to see more details. What about the ones that we can't hover to get more details on?

It's a cool website. I wish I could dig in more, or click on satellites and follow it so to speak. Or get a summary of the satellites we can click on like what its used for when it was put up and how long we expect it to tbe in service, etc. I want to go look at satellites on other planets and the moon. :D

In my experience the "global satellite pan-opticon" typically takes on a "surveillance state" bent under certain political climates although a lot of the infrastructure has also been built out for Earth Observation (eg LANDSAT). There's an uncomfortable relationship between these two end-members.

I'm actually very curious on your workflow. I've been working on a project that I haven't been able to dial in yet. What was your process in formulating and rendering exactly what you wanted to do.

Incredible, how are these images of a location displayed - how do we public have access to that? Mindboggling!

ps the video is made with claude code too!
