Yes, so I’m taking every telescope/radio/radar reading I’m allowed to redistribute and then collecting them into a time series database and fetching the most recent reading for each sat into a text file. That’s the TLE download in the public API. Then I use Rust WASM to propagate those readings into positions that are synced with the viewer time. This allows us to very roughly forecast where they will be for the next couple days.
It’s cool because it’s too much data to transfer over the network, so we only transfer the most recent reading and then calculate positions live in the browser.
