Could you build this?
Partial A web map displaying satellite coordinates is vibe-codeable, but calculating high-precision orbital propagations (SGP4/SDP4) and pass predictions validated against Skyfield requires solid astrodynamics math.
What it would actually take: Requires an implementation of SGP4/SDP4 propagation algorithms in TypeScript along with coordinate transformation matrices (TEME to ITRS/WGS84). To support thousands of orbiting bodies in real time, it requires Web Workers or WebGL computation pipelines and fetching fresh TLE/orbital element sets from Space-Track or Celestrak.
