Satellite pass widget — embed any satellite

Put a live “next pass” card for any tracked satellite — the ISS, a ham-radio bird like HADES-SA, a weather sat — on your own site, for any city, in 10 languages. One copy-paste iframe, free, no signup. The pass times are computed live from the latest orbital data (CelesTrak/SGP4).

Live preview

This is the real widget — HADES-SA (Spain-OSCAR 127) over Madrid, in Spanish:

Copy-paste code

<iframe src="https://gocosmik.com/embed/sat/hades-sa/madrid?lang=es"
  width="360" height="150" frameborder="0" loading="lazy"
  title="Próximo paso de HADES-SA sobre Madrid"></iframe>

Paste it anywhere in your HTML. The Cosmik credit link is inside the widget (that's the deal — the widget is free, it just links back).

The URL structure

https://gocosmik.com/embed/sat/{satellite}/{city}?lang={lang}

1. {satellite} — which satellite

Use a supported slug or any NORAD catalogue number. Currently supported by slug:

hades-sa — HADES-SA (SO-127) (NORAD 68446)
iss — International Space Station (NORAD 25544)

Want another satellite added by slug, or a per-satellite page? Ask us — if it's tracked, we can add it.

2. {city} — which location

Any city slug we support — the same one in its URL on our ISS pass pages (e.g. madrid, valencia, london, tokyo). Pass times and the clock are shown in that city's local time automatically.

3. ?lang= — the language (optional)

Add ?lang=so the whole card — title, labels and date format — matches your site's language. Default is English. Supported:

en — English
es — Español
fr — Français
it — Italiano
de — Deutsch
pt — Português
ru — Русский
pl — Polski
nl — Nederlands
ja — 日本語

Example — Spanish for a satellite over Valencia: /embed/sat/hades-sa/valencia?lang=es

Sizing

The card is ~320px wide and ~130px tall. Set width="100%" to fill its container, or a fixed width="360". Keep height around 150 so nothing clips. It has a transparent-friendly dark card style that sits well on most sites.

Data & licensing

Pass predictions are computed live with SGP4 from CelesTrak/NORAD orbital elements, refreshed every 10 minutes. The data is free to use under CC-BY— a link back to Cosmik is all we ask, and it's already baked into the widget. See the data page and the full widget gallery(aurora, ISS, launch & eclipse countdowns).
