Earth observation satellite
Let an agent explain Earth observation satellites and their instruments, relay major programmes and data sources, describe applications and policy, and distinguish Earth observation from communications, navigation and reconnaissance satellites.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain Earth observation satellites and their instruments, relay major programmes and data sources, describe applications and policy, and distinguish Earth observation from communications, navigation and reconnaissance satellites.
An artificial satellite designed to observe the Earth from orbit for environmental monitoring, meteorology, mapping, agriculture, disaster response, geomagnetic measurement and security, carrying optical, radar, thermal, hyperspectral or magnetic instruments, in programmes such as Landsat, the European Sentinel series including planned Sentinel-10 and Sentinel-11, French Pleiades, Korean KOMPSAT and commercial constellations such as Satellogic NuSat; Earth observation data underpin climate science and many public services.
What it is for: Observing the Earth from orbit.
It can be explain instruments and orbits; relay programmes and data access; describe applications; distinguish from other satellites.
Distinguishing features
Earth-pointing sensors
Sun-synchronous orbits common
Open data programmes
Commercial constellations
What it looks like
A spacecraft with solar panels and sensors pointed at Earth, often in polar orbit.
Physical character
Earth observation satellites in orbit: over 1000 count - estimates including small satellites
Sentinel-2 resolution: 10 m - visible bands
How it is recognised
Satellite observing Earth
Landsat, Sentinel, Pleiades, KOMPSAT, NuSat, geomagnetic satellites
Communications and navigation satellites serve other purposes; reconnaissance satellites are military
