I think modern satellites have matrix sensors

• kevin_thibedeau 5y ago
  It depends on the satellite. Weather satellites in GEO do because they aren't moving relative to the surface and they have time constraints for scanning the full earth disc. Higher resolution imaging satellites use linear sensors. However, they use TDI imaging which at a low level makes them superficially like an area array with limited vertical resolution but the light collection is still fundamentally different.
