A circular orbit at an altitude of approximately 35,786 km above Earth's equator where a satellite's orbital period exactly matches Earth's rotation period (~23h 56m). A satellite in GEO appears stationary relative to a point on the ground. Used for weather satellites (NOAA GOES, JMA Himawari), communications, and broadcast TV.
In LaunchDetect
NOAA GOES-19 (75.2W) and NOAA GOES-18 (137.2W) are LaunchDetect's GEO data sources, along with JMA Himawari-9 (140.7E). All three view Earth continuously from a fixed perspective, ideal for thermal-detection monitoring.
