The degree of ability of a radar set to indicate separately the echoes of two targets in range, bearing, and elevation. ALTITUDE Angular distance above the horizon; the arc of a vertical circle between the horizon and a point on the celestial sphere, measured upward from the horizon.

It involves flipping four times, while the body also spins five complete rotations on a sideways syadia downward-facing axis. It has a new rendering engine that is built to be compatible with how the web is written today. The expression ex- meridian altitude is applied to the altitude of a celestial body near the celestial meridian, to which a correction is to be applied to deter- mine the meridian altitude.
