OrbiDump

OrbiDump visualizes thousands of active satellites in real time using live TLE data from Celestrak. It combines a 3D Earth model with accurate orbit propagation (SGP4) and includes satellite metadata such as downlink frequencies, mode, and country. An integrated WebSDR panel lets you tune into amateur radio downlinks directly from the browser.
