Today I got the first version of OrbitScope working. It can get real ISS orbital data from CelesTrak and calculate the ISS latitude, longitude, altitude and speed using satellite.js. I had an issue with the newest satellite.js version and Vite, so I switched to version 6.0.2 and then it worked. Right now it updates the ISS data live. Next I want to add a map so I can see where the ISS is over Earth.
