The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting.

NOAA-20, designated JPSS-1 prior to launch, is the first of the United States National Oceanic and Atmospheric Administration's latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites called the Joint Polar Satellite System.
HRPT transmissions are available around the world and are available from both polar and geostationary weather satellites. The polar satellites rotate in orbits that allow each location on Earth to be covered by the weather satellite twice per day while the geostationary satellites remain in one location at the equator taking weather images of ...
The geostationary Himawari 8 satellite's first true-colour composite PNG image The geostationary GOES-17 satellite's Level 1B Calibrated Radiances - True Colour Composite PNG image. Each meteorological satellite is designed to use one of two different classes of orbit: geostationary and polar orbiting.
To avoid confusion, geosynchronous satellites that are not in geostationary orbit are sometimes referred to as being in an inclined geostationary orbit (IGSO). Some of these satellites are separated from each other by as little as 0.1° longitude. This corresponds to an inter-satellite spacing of approximately 73 km.

Graveyard orbit (or disposal, junk orbit) : An orbit that satellites are moved into at the end of their operation. For geostationary satellites a few hundred kilometers above geosynchronous orbit. [26] [27] Parking orbit, a temporary orbit. Transfer orbit, an orbit used during an orbital maneuver from one orbit to another.
Geostationary satellites, providing a continuous view of the Earth disc from a stationary position in space. Polar-orbiting satellites, flying at a much lower altitude, sending back more precise details about atmospheric temperature and moisture profiles, although with less frequent global coverage.
