Live 3D satellite globe
Explore more than 15,400 active satellites on an interactive 3D globe, with objects positioned in real time from orbital elements.
azmth
azmth is a free, real-time satellite tracker with an interactive 3D globe, pass predictions for your location, and live views of major spacecraft and constellations.
Overview
azmth is a free, real-time satellite tracker for exploring Earth-orbiting objects on an interactive 3D globe. It follows more than 15,400 active satellites, predicts passes over your location, and surfaces object-specific views for major spacecraft and constellations.
The product is aimed at people who want a practical way to inspect where satellites are, when they will be visible, and how different orbit regimes behave. It also includes a separate statistics view that summarizes the current active satellite catalog by constellation, country or operator, orbit regime, and launch decade.
Features
Object and constellation trackers
View dedicated trackers for the ISS, Hubble, Tiangong, Starlink, GPS, Amazon Kuiper, Qianfan, OneWeb, and the James Webb Space Telescope.
Local pass prediction
See when a satellite will pass over your location, with pass predictions generated from the current catalog.
Starlink train detection
Detect freshly launched Starlink trains and track the next visible “string of pearls” pass over your location.
Orbit and visibility context
Use orbit and visibility context such as LEO, MEO, GEO, HEO classifications and visible/daytime/in-shadow labels.
Browser-side orbital computation
Work from a catalog refreshed every 2 hours from CelesTrak data, with positions computed in the browser via SGP4/SDP4 propagation.
Use cases
Follow the ISS
Check the International Space Station’s current position and see when it will pass over your location tonight.
Monitor Starlink launches
Track Starlink satellites and newly launched trains, including the next “string of pearls” pass visible from your area.
Study constellations
Inspect a constellation such as GPS, OneWeb, Kuiper, or Qianfan on a 3D globe and compare orbital layouts.
Review satellite counts
Look up how many active satellites are in orbit by country, operator, constellation, or orbit regime using the statistics view.

Use the browser-based tracker to understand orbital mechanics and locate satellites without creating an account.
Pros and Cons
Pros
- No signup is required.
- No advertising is shown.
- It offers both a live globe and dedicated object trackers.
- Catalog data refreshes every 2 hours.
- Pass predictions and orbit context are built into the experience.
Cons
- Visibility labels are geometric estimates and do not yet model per-satellite brightness.
- Accuracy can drop for objects with stale orbital elements or rapidly decaying orbits.
- The site is focused on active satellites and does not cover the much larger debris population in the main tracking views.
FAQ
Do I need an account to use azmth?
No. The site says there is no signup and no advertising, and the tracker is described as free to use.
What does azmth show?
The tracker is built around real-time satellite tracking on an interactive 3D globe. It also includes pass predictions for your location and dedicated views for specific objects and constellations.
How does azmth get its satellite data?
It is designed as a browser-based experience. Satellite positions are computed in your browser from catalog data that the site refreshes every 2 hours.
What are the main limitations?
The site can show live positions, pass predictions, and orbit details for active satellites, but it does not model per-satellite brightness yet. Accuracy also declines when orbital elements are stale or the object is rapidly decaying.
Is there a pricing plan?
The pricing page is sparse, but the site presents the project as free and supported by donations, rather than a traditional multi-tier SaaS product.
