Show HN: Every satellite that passed over any place this week, and its photos
hey HN, i built this because I'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 / Landsat / NASA images from those passes. fun fact: all ~17k objects in orbit are drawn on the…
A satellite enthusiast created an online tool to display every satellite that passed over a specific location over the past week. The tool utilizes the SGP4 algorithm to track over 17,000 objects orbiting Earth, and it pulls real-time images from Sentinel-2, Landsat, and NASA satellites. The application runs in the browser and can generate results in just half a second.
The developer behind the tool, who identifies as a "satellite nerd," noted that Sentinel-2 timestamps can be off by 5-10 minutes from the actual satellite crossing time, requiring additional calculations to ensure accuracy. The tool only displays genuine images captured by these satellites and never stores the user's location. The source code for the project is available on GitHub, and the developer is open to receiving feedback, contributions, and other forms of support. The tool was discussed on Hacker News, with the discussion thread accessible at the provided link.
