It is convenient to define the orientation of an ECI frame using the Earth's orbit plane and the orientation of the Earth's rotational axis in space. The Earth's orbit plane is called the ecliptic, and it does not coincide with the Earth's equatorial plane. The angle between the Earth's equatorial plane and the ecliptic, ε, is called the obliquity of the ecliptic and ε ≈ 23.4°. An equinox occurs when the earth is at a position in its orbit such that a vector from the earth to… WebA reference frame is a like a fixed point. Properties of other objects such as: position, velocity etc. are measured using the point. It is so because no point in the universe is stationary or static. Every point is moving depending on another 'so called' static point. See it like this: you are going to a amusement park in a bus with your friend.
