   Dec 17, 2012 · A polar orbit is an orbit that passes over the Earth’s poles, traveling from north to south. Sun-synchronous orbit (SSO) is a type of polar LEO. In SSO, the Earth’s uneven gravitational field “twists” the orbit of a satellite at a rate of one revolution per year.

   Polar orbits are 90 degree inclination orbits, useful for spacecraft that carry out mapping or surveillance operations. Since the orbital plane is nominally fixed in inertial space, the planet rotates below a polar orbit, allowing the spacecraft low-altitude access to virtually every point on the surface.

   Jul 7, 2010 · Any satellite with an orbital path going over or near the poles maintains a polar orbit. Polar orbits are usually low Earth orbits. Eventually, Earth’s entire surface passes under a satellite in polar orbit.

   Kuafu B1 and B2 will be placed in polar orbits. The project is named after Kua Fu (夸父), a giant in Chinese mythology who died trying to catch the Sun. Autotranslators translate Kua Fu (夸父) as "braggadocio" or "boast father".

   For example, look for perigee and apogee at Earth, perijove and apojove at Jupiter, periselene and apselene or perilune and apolune in lunar orbit, pericrone and apocrone if you're orbiting Saturn, and perihelion and aphelion if you're orbiting the Sun, and so on.

   Which satellite maintains a polar orbit?

   • Any satellite with an orbital path going over or near the poles maintains a polar orbit. Polar orbits are usually low Earth orbits. Eventually, Earth’s entire surface passes under a satellite in polar orbit. When a satellite orbits Earth, the path it takes makes an angle with the equator.

   How does a satellite go to a polar orbit?

   • Satellites headed for GEO first go to an elliptical orbit with an apogee about 37,015 km. Firing the rocket engines at apogee then makes the orbit round. Geosynchronous orbits are also called geostationary. Any satellite with an orbital path going over or near the poles maintains a polar orbit.

   What is an object in an orbit called?

   • An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them. A satellite can also be man-made, like the International Space Station. Planets, comets, asteroids and other objects in the solar system orbit the sun.

   What are the different types of orbits?

   • There are different types of orbits. The type that a satellite is launched into depends on its mission. Low Earth Orbit (LEO) is the simplest orbit to achieve. The majority of artificial objects orbiting the Earth are in the LEO “corridor.” That is an area between 160 km and 1 000 km above the Earth’s surface.

   How does gravitational influence affect a spacecraft's orbit?

   • Other bodies such as the Sun, or natural satellites, contribute their gravitational influences to a spacecraft in orbit about a planet. It is possible to choose the parameters of a spacecraft's orbit to take advantage of some or all of these gravitational influences to induce precession, which causes a useful motion of the orbital plane.
