Deep Space Network Coverage — 2D Polar View & Elevation Timeline

This 2D companion looks straight down Earth's spin axis at the three real NASA Deep Space Network complexes — Goldstone in California, Madrid in Spain, and Canberra in Australia — as they orbit the centre of a polar-projection map once every simulated day. A live elevation-vs-time strip chart underneath tracks all three stations' angle to a distant spacecraft at a chosen declination, using the same spherical-astronomy elevation formula as the full 3D globe. Watch stations rise above the elevation mask, hold the lock, and hand off to the next station as they set, and see exactly why three antenna complexes spaced ~120° apart in longitude are what keeps missions like Voyager and Perseverance in near-continuous contact instead of going dark for hours at a time.
