Four steps, every night

What happensbefore it rings.

The sky maths runs at night, so the set can stay quiet all day. Here is what happens between the 2 am update and the chime.

  1. Orbital elements update overnight

    At 2 am the set fetches fresh orbital elements for about 9,000 objects over Wi-Fi. It takes under a minute.

    Updated 02:00 local
  2. It predicts passes for your spot

    GPS fixes your exact position, so every prediction is for your garden, not your city. They hold for two weeks without Wi-Fi.

  3. It keeps only what you can see

    A pass counts only if your sky is dark, the satellite is lit by the sun and it climbs above 20°. Most never make the cut.

    Above 20° only
  4. A chime, then the dial points you

    Two minutes before, one soft chime. The dial swings to the bearing and the tube shows the height: Look up · NNE · 42°.

Tonight, overyour city.

Pick a city and the tube draws the next three passes worth going outside for. Skyset does this for your exact spot, every night.
