Detailed explanation-1: -The best examples of LEO satellites are the Hubble space telescope, the Spot family of satellites (Earth imaging and survey) and military observation satellites. As previously mentioned, a specific orbit called “polar orbit” is inclined at ∼90° to the equatorial plane, covering both poles.
Detailed explanation-2: -While polar orbits have an inclination of about 90 degrees to the equator, geostationary orbits match the rotation of the Earth. A sun-synchronous orbit passes by any given point with the same local solar time, which is useful for consistent lighting and sun angle.
Detailed explanation-3: -Near-Polar Orbits. The other popular orbit type for remote sensing is near-polar. The name is fairly self-explanatory; these are orbits with high inclination angles with an sub-orbital track that almost goes across the poles.
Detailed explanation-4: -High Earth Orbit. When a satellite reaches exactly 42, 164 kilometers from the center of the Earth (about 36, 000 kilometers from Earth’s surface), it enters a sort of “sweet spot” in which its orbit matches Earth’s rotation.
