I'm 20, self taught, and I built a live satellite tracker (SGP4 + real TLE data + Doppler). Would love if you tried to break it.
Hey everyone. I'm Nolan, 20, from Belgium. I'm fully self taught, I learned everything I know about code and orbital mechanics on my own, mostly late at night because space is the one thing my brain won't let go of.
I made this: orbitinsight.vercel.app
It's a satellite tracker that runs in your browser and updates in real time. It pulls live TLE data from Celestrak, uses SGP4 to compute where the satellites actually are, and calculates the Doppler shift. I also added a small physics sandbox so you can mess with orbital parameters and watch the trajectory change.
I know it's nowhere near the big established tools yet. I didn't build it to compete, I built it to learn and because I wanted orbital mechanics to feel real instead of just formulas on paper. I work on it pretty much every day so it keeps getting better.
Reason I'm posting is I want real feedback from people who know this way better than me. What's wrong or inaccurate? What's missing? If you actually track or observe satellites, what would make something like this useful to you instead of just a cool demo? Be brutal if you need to, that's what helps me the most.
Thanks for reading.
