In what unit is the right ascension measured
Web27 aug. 2003 · r is the position vector of the satellite relative to the center of the earth. The components of r and, especially, those of its time derivatives r ˙ = v and r ¨ = a, must be measured in a nonrotating frame attached to the earth.A commonly used nonrotating right-handed Cartesian coordinate system is the geocentric equatorial frame shown in … WebAt first glance, this system of uniquely positioning an object through two coordinates appears easy to implement and maintain. However, the equatorial coordinate system is tied to the orientation of the Earth in space, and this changes over a period of 26,000 years due to the precession of the Earth’s axis.We therefore need to append an additional piece of …
