SSO is a polar orbit passing a given point at the same local solar time.
GEO altitude is 35,786 km above the equator.
The standard four resolutions are spatial, spectral, radiometric, and temporal.
D = H × β, with β as IFOV in radians.
GEO is a special case of GSO, fixed over the equator; GSO can have inclination.
Microwave wavelengths are not blocked by clouds, enabling all-weather imaging (SAR).
Landsat-8/9 carry OLI-2 and TIRS-2 for high-quality Earth imaging.
SSO generally operates at 600–900 km altitude with retrograde inclination.
Revisit is governed by orbital geometry and swath width; higher swath can improve temporal coverage.
GEO satellites enable real-time weather data and constant hemispheric communication links.
Platforms are categorized as ground-based, airborne, or spaceborne based on altitude.
SSO ensures similar illumination by precessing with Earth’s orbit.
Spaceborne platforms operate well above the atmosphere.
TIR sensors detect emitted heat from objects.
GSD is the ground area covered by a single pixel.
GEO provides constant viewing of a hemisphere for weather.
Proximity yields centimeter-level detail for airborne sensing.
Passive relies on external illumination; active emits its own energy.
Temporal resolution refers to revisit frequency.
Landsat is a long-running Earth-imaging program.
