Satellite

Satellites on real orbits drawn with code: the Earth from space with its shells of satellites, every orbit solved from Kepler's equation and timed in whole bars of your song, so passes land on the beat and every link lights on the drop. Six ways to watch them: the orbits round the Earth, the ground tracks on a world map, a mega-constellation of hundreds, a mission control room's wall, a satellite unfolding its panels and a night sky with satellites crossing among the stars.

Orbit View

The Earth from space with its shells of satellites: a space station and a weather satellite circling once a bar, navigation satellites at half a day, a long ellipse and the geostationary ring hanging over one place as the Earth turns under it. The highs light the trails and the drop links every satellite to its neighbours.

Classic Studio

Ground Track

A world map with each satellite's track drawn as it flies, drifting west orbit after orbit as the Earth turns: the space station's waves, a polar weather satellite, a long ellipse's loop and a geosynchronous figure eight. Coverage circles swell with the bass and cities light as a pass goes over.

Classic Studio

Shell Constellation

A mega-constellation round a night Earth: hundreds of satellites in rings of planes. The planes light in turn round the bar, the build launches new trains up into the shells and the drop draws the whole mesh of links between them.

Classic Studio

Mission Control

A control room's lit wall: the world map with the tracks, telemetry from the real orbit ticking on the beat, a sky plot of the pass and a pass clock counting the bar, while the next pass's arc lights up through the build.

Deploy

Close on a satellite leaving its upper stage high over the Earth: it springs free on the phrase, its solar panels unfold one bar at a time, its antenna sweeps with the mids and its thrusters puff on the kick.

Classic Studio

Night Pass

A night sky from a hillside after dusk: the real stars, the Milky Way, and satellites crossing among them on the beat, lit by a sun already set, fading as they pass into the Earth's shadow. On the drop one catches the sun in a brief flare.
