Want this question answered?
a polar orbit is not a type of geosyhchronous orbit.
Polar orbit
From a polar orbit, a satellite can observe over time anypoint on the globe from directly above it.
A polar orbit or high-inclination orbit. In polar orbit, the satellite passes over the world from pole to pole, while the Earth spins beneath it. Each orbit would cover a different area.
A satellite in polar orbit passes over the poles.A geosynchronous orbit follows the equator and at such an altitude its orbital period is one day long and remains in the same position relative to the ground.
Circum polar satellites.
A synchronous polar orbit satallite crosses the equator at the same time each day while the sun synchronous polar satellite appears in the sky at the same time every few days. the sun synchronous allow for greater temporal and spatial monitoring under same conditions and also have finer resolution as the polar synchronous imagery is at the continental scale.
The polar orbit so that it can measure cold and hot points around the entire earth :)
As many times as necessary in order to get the ground map. I am no expert but one orbit from north to south (since this is polar) must depend on the impulse provided by the final kick to put it into polar orbit. TLDR is varies (I believe this is referred to as it's period) try examining various polar sats on file at wiki to see if this is correct. I to would like to know!
PSLV-C11
it is too cold and there is no power lines to get signal
If the satellite is in an orbit that takes it over the North and South Poles, it will eventually cover all parts of the Earth as the Earth spins beneath it. This kind of orbit is called a polar orbit.
