Polar satellites, orbiting over the polar region (first link), takes approximately 100 minutes to do one complete pass at 25-degrees Earth rotational difference, to map the full section.(second link)
For other satellites, it can take 90 minutes just to re-position a satellite to cover a new region, and THEN begin mapping. But the polar satellites stay in a constant orbit.

What is a polar satellite State two uses of a polar satellite?
A polar satellite is a type of satellite that orbits the Earth in a north-south direction, passing over both poles. Two uses of polar satellites are weather forecasting, as they can provide global coverage of weather patterns, and environmental monitoring, such as tracking changes in ice caps and studying climate change.
What is polar satellite?
The Polar Satellite was the name for a NASA science spacecraft which was launched February 24, 1996, to observe the magnetosphere. Polar was in a 86 degree orbital inclination with an orbital period of roughly 17.5 hours. The Polar Mission Operations were terminated on April 28th, 2008. Any satellite with a 90 degree tilt is considered to have a "polar orbit", as it allows the satellite to view every latitude of the Earth including the north and south poles.
Some satellites are put into an orbit around the earths poles what is this type of orbit called?
A satellite orbiting around the Earth's poles is in a polar orbit. This type of orbit allows the satellite to pass over different parts of the Earth as it rotates below. Polar orbits are often used for Earth observation and surveillance satellites.
What orbit would allow a satellite to see all parts of the globe?
A geostationary orbit would allow a satellite to see all parts of the globe as it orbits the Earth at the same speed that the Earth rotates. This means the satellite remains fixed above the same point on the equator, providing continuous coverage of that area.
What is a polar orbit used for?
A polar orbit is used for various purposes, such as Earth observation, weather monitoring, and environmental research. It provides global coverage as it allows a satellite to pass over the entire surface of the Earth while remaining in a north-south direction. This type of orbit is particularly useful for capturing images of the entire planet or studying changes in polar regions.
How is a weather satellite in polar orbit able to view Earths surface?
From the question, I'm guessing that when the questioner reads the term "polar orbit", he's picturing the satellite doing a little tiny circle in the sky over the North Pole. This is not an accurate understanding of the term. Remember that the center of the orbit of an artificial satellite has to be at the center of the earth. A 'polar orbit' is an orbit that covers both poles. If you picture the globe of the earth, the satellite's orbit is a circle standing up, with the satellite traveling up and down, passing over both poles in each complete revolution of the earth. As the earth rotates, every point on earth passes under the orbit, and sooner or later, every point on earth will be visible from the satellite.

Why are polar satellites called Detective satellite?
A satellite in a polar orbit orbits from north to south. As the earth turns, it passes over all the surface area of the earth. Therefore, polar orbits are ideal for detecting things on the planet's surface.
Is IRS a polar satellite or equatorial satellite?
It is polar orbiting.
Why a satellite in a polar orbit traces a curved path over the surface of Earth?
A satellite in a polar orbit traces a curved path over the Earth's surface due to the rotation of the Earth beneath it. As the satellite moves in its orbit from pole to pole, the Earth rotates, causing the satellite's ground track to appear as a series of curved lines. This effect is a result of the Earth's spherical shape and rotation, which means that while the satellite follows a straight line in space, the surface of the Earth is moving underneath it. Consequently, the satellite covers different longitudinal positions as it orbits, creating a curved trajectory relative to the Earth's surface.

What is polar satelite?
Which are usually launched in polar orbite and these polar orbit lie around north and south poles of earth and their angle with equitorial plane is 90'
Does a satellite in a polar orbit remain at the same point of a equator?
No, a satellite in a polar orbit does not remain at the same point over the equator. Instead, it travels over the Earth's poles, allowing it to pass over different points on the equator as the Earth rotates beneath it. This means that the satellite covers a different section of the Earth's surface with each orbit, providing global coverage over time.
When was Polar Satellite Launch Vehicle created?
Polar Satellite Launch Vehicle was created in 1993.
What are the main differences between geostationary orbit and polar orbit?
A polar orbit is an Orbit in which a Satellite passes above or nearly above both of the Geographical poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun being orbited on each revolution. It therefore has an Inclination of (or very close to) 90 degrees to the Equator. Except in the special case of a polar Geosynchronous orbit, a satellite in a polar orbit will pass over the equator at a different Longitude on each of its orbits.A geostationary orbit (GEO) is a circular orbit directly above the Earth's Equator From the ground, a geostationary object appears motionless in the sky and is therefore the Orbit of most interest to operators of Communication Satellites. Their orbital periods (time taken to revolve around earth) is exactly the same as the planet's (such as Earth's) rotational period. The Geosynchronous orbit is approximately 36,000 km above Earth's surface.geostionary satellites are positioned at an exact height above the earth, at this height they orbit the earth at the same speed at which the earth rotates on its axis whereas polar satellites have a much lower orbit, orbiting the earth quite quickly, scanning different areas of the earth at fairly infrequent periods.
Why for polar orbit rate of regression is zero?
In a polar orbit, the satellite travels over the Earth's poles, maintaining a fixed trajectory relative to Earth's rotation. As the Earth rotates underneath the satellite, the ground track shifts westward, allowing the satellite to cover different longitudinal areas with each pass. Since the orbit's inclination is 90 degrees, the rate of regression—the apparent westward movement of the satellite's orbit due to Earth's rotation—becomes zero, as the satellite's path remains aligned with the Earth's rotational axis. This results in consistent coverage of the same longitudinal points over time.
