Show HN: Every satellite that passed over any place this week, and its photos
95 points by a585gupt
A new tool allows users to input any location and retrieve a list of satellites that passed overhead in the past week, along with corresponding images from Sentinel-2, Landsat, and NASA. The search algorithm, based on the SGP4 model from the CelesTrak catalog, has proven accurate, missing no passes during testing across various geographic challenges. The system can access approximately 17,000 satellite objects and provides real-time results within half a second.
