hey HN, i built this because I&#x27;m a satellite nerd who was bored this past weekend.type in any place and it finds every satellite that passed over it in the last 7 days (SGP4 on the CelesTrak catalog, tracking 17k+ objects and runs in your browser in about half a second), then pulls the real Sentinel-2 &#x2F; Landsat &#x2F; NASA images from those passes.fun fact: all ~17k objects in orbit are drawn on the GPU, solving Kepler&#x27;s equation every frame. also cool is that Sentinel-2 timestamps are often 5-10 min off from when the sat actually crosses your spot, so some cool math was involved in making it accurate on the site.it only shows real images taken from those exact satellites, and it never store your location.code: <a href="https:&#x2F;&#x2F;github.com&#x2F;dev-Armaan&#x2F;satellites" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dev-Armaan&#x2F;satellites</a>would love feedback, contributions, or whatever else you guys can offer!
