Weather Satellite Directory: Different Orbits for Different Observations
Weather and environmental satellites observe Earth with very different orbital strategies. Some remain near one longitude from geostationary orbit, while others repeatedly sweep over changing parts of the planet from low or near-polar orbits.
Polar versus geostationary weather satellites
Geostationary weather spacecraft orbit roughly 35,786 kilometres above the equator and have an orbital period that matches Earth's rotation, so they appear nearly stationary in the sky. Polar and near-polar satellites orbit much lower and build global coverage as Earth turns under their path.
An orbital tracker shows where the spacecraft platform is; it does not display calibrated weather imagery or produce forecasts. Official meteorological services combine satellite observations with radar, surface observations, aircraft, ocean measurements and numerical models.
Use the weather tracking tools
Open the dedicated Weather Satellite Trackers page to select a spacecraft, or use the GOES Satellite Tracker for the geostationary U.S. weather fleet. The geostationary directory is useful for comparing their high-altitude geometry with lower polar-orbiting spacecraft.
How this directory works
Choose a specific weather spacecraft because this category mixes very different orbital regimes. An individual tracker can show whether the selected platform is moving through a polar orbit or remaining near a geostationary longitude; operational imagery and forecasts come from meteorological agencies.
Orbit calculations describe the spacecraft platform, not the quality or freshness of weather products. Element age matters differently for low-orbit and geostationary objects, while instrument status and forecast use should be checked with the operating agency.
What to remember about accuracy
Frequently asked questions
Is the position direct spacecraft telemetry?
No. The live map is calculated from public orbital elements.
Does appearing in this directory mean a satellite is operational?
No. Catalog membership and mission status are different things.
Can I track one object in more detail?
Yes. Select a weather satellite and open its individual tracker to calculate its current position and observer geometry.
