WebDec 17, 2024 · What is a polar-orbiting satellite? Polar-orbiting satellites provide a more global view of Earth, circling at near-polar inclination (the angle between the equatorial plane and the satellite orbital plane — a true polar orbit has an inclination of 90 degrees). WebAn inclination of zero degrees indicates an orbit about the primary's equator in the same direction as the primary's rotation, a direction called prograde (or direct). An inclination of 90 degrees indicates a polar orbit. An inclination of 180 degrees indicates a retrograde equatorial orbit.

WebFeb 16, 2024 · The satellite orbit inclination is assumed to be within 0.1 deg of polar, and the altitude is chosen to be somewhat lower than the early altitude for GRACE Follow-On. However, so that the satellites can be flown in a drag-free mode with a quite simple thruster system, altitudes below 400 km were not considered.

WebInclination can range from 0 to 180 degrees, where a 90-degree inclination is called a polar orbit. 180 degrees of inclination is also an equatorial orbit but the satellite orbital direction is the opposite of the 0-degree equatorial orbit. As 0 to 90-degree inclination looks symmetric to the 90 to 180-degree inclination, the inclination of ...
