hey HN, i built this because I&#x27;m a satellite nerd who was bored this past weekend.<p>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.<p>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.<p>it only shows real images taken from those exact satellites, and it never store your location.<p>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><p>would love feedback, contributions, or whatever else you guys can offer!
