Polar orbit - Wikipedia
A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution.
#29. Polar Orbiting Satellites - NASA
2001年11月25日 · Known as the National Polar-orbiting Operational Environmental Satellite System or NPOESS ("en-poss") for short, the satellites of that mission, to be launched in the first decade of the 21st century, will carry a sophisticated complement of scientific instruments.

2020年3月30日 · Satellites in a polar orbit do not have to pass the North and South Pole precisely; even a deviation within 20 to 30 degrees is still classed as a polar orbit. Polar orbits are a type of low Earth orbit, as they are at low altitudes between 200 to 1000 km.
Polar Operational Environmental Satellites (POES) Overview
Polar orbiting satellites constantly circle the Earth in an almost north-south orbit, passing close to both poles. The POES satellite system offers the advantage of daily global coverage, by making nearly polar orbits 14 times per day approximately 520 miles above the surface of the Earth.
Catalog of Earth Satellite Orbits - NASA Earth Observatory
Many of the satellites in NASA’s Earth Observing System have a nearly polar orbit. In this highly inclined orbit, the satellite moves around the Earth from pole to pole, taking about 99 minutes to complete an orbit. During one half of the orbit, the satellite views the daytime side of the Earth.
The World in Real-Time | NESDIS - National Environmental Satellite ...
The World in Real-Time global map utilizes Geographic Information Systems (GIS) to provide a live satellite view of select data from geostationary and polar-orbiting NOAA satellites and partner satellites of the Earth from space.

3 天之前 · Polar Orbit. Within 30 degrees of the Earth’s poles, the polar orbit is used for satellites providing reconnaissance, weather tracking, measuring atmospheric conditions, and long-term Earth observation. Sun-Synchronous Orbit (SSO)
Polar Orbit vs Sun Synchronous Orbit - GIS Geography
A polar orbit travels north-south over the poles and takes approximately an hour and a half for a full rotation. As the satellite is in orbit, the Earth is rotating beneath it. As a result, a satellite can observe the entire Earth’s surface (off-nadir) in a time span of 24 hours.
Chapter 5: Planetary Orbits - NASA Science
An inclination of 90 degrees indicates a polar orbit, in which the spacecraft passes over the north and south poles of the planet. An inclination of 180 degrees indicates a retrograde equatorial orbit.
Polar Orbit – Definition & Detailed Explanation - Sentinel Mission
2024年3月22日 · A polar orbit is a type of orbit in which a satellite passes over the Earth’s poles as it orbits the planet. This means that the satellite’s path is perpendicular to the equator, allowing it to cover the entire surface of the Earth over time.
