Earth Observation Satellite Tracker — Landsat, Sentinel, and Remote Sensing

Earth observation satellites provide a continuous stream of imagery and data about our planet's land surfaces, oceans, atmosphere, and ice sheets. These missions support agriculture, forestry, urban planning, disaster response, and climate monitoring with unprecedented detail and regularity.

NASA's Landsat program, operating since 1972, holds the longest continuous record of Earth imagery from space. The European Copernicus program's Sentinel satellites provide free, open-access radar and optical imagery updated every few days. Together with commercial operators like Planet Labs and Maxar, the Earth observation fleet delivers daily global coverage at resolutions from hundreds of meters down to sub-meter detail.

This tracker shows active Earth observation satellites in real time, revealing the dense network of remote sensing platforms scanning the planet. See their sun-synchronous orbits, ground tracks, and the swath of Earth they can observe on each pass.
