In the ECI, the \(Z\) axis points towards the North pole and the \(X\)-\(Y\) plane is in the same plane as the equator. Since this is an inertial frame, it is fixed in place with respect to the celestial sphere, the stars surrounding the earth. goan pork recipes
Equatorial coordinate system - Wikipedia
These frames are location dependent. For movements around the globe, like air or sea navigation, the frames are defined as tangent to the lines of geographical coordinates: • East-West tangent to parallels, • North-South tangent to meridians, and • Up-Down in the direction normal to the oblate spheroid used as Earth's ellipsoid, which does not generally pass through the center of the Earth. The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass. Its most common use is in tracking the orbits of satellites and in satellite navigation systems for measuring locations on the surface of th… WebA right-handed convention, specifying a y axis 90° to the east in the fundamental plane and a z axis along Earth 's north polar axis. This frame is in every way equivalent to the ξ, η, ζ frame, above, except that the origin is removed to the centre of the Sun. It is commonly used in planetary orbit calculation. goan pork vindaloo americas test kitchen
