This read-only value, in degrees, reports the elevation angle of a specific tracked GPS satellite above the local horizontal plane, as seen from the antenna. An admin cares because satellites at very low elevation angles are more easily blocked by buildings or terrain, so this helps explain weak or unreliable signal-to-noise readings for that satellite. For example, if several satellites showing poor signal-to-noise ratio all have low elevation angles, the admin might conclude the antenna's horizon view is obstructed rather than suspecting a hardware fault.
