glideslope
The ILS component that defines the descent angle to the runway, usually three degrees.

The glideslope antenna sits beside the touchdown zone. Three degrees puts an aircraft roughly 300 feet up a mile out, which is the number that decides how much lens a spotter needs at a given distance from the threshold. A few runways use a steeper angle for terrain or noise reasons.
