GS stands for which term in air navigation?

Explanation:
GS stands for the glideslope, the vertical guidance component of an instrument landing system. The glideslope provides a precise descent angle to the runway, so you can fly the correct vertical path while the localizer handles the horizontal alignment. On your navigation display, the glideslope indication shows how far you are off the path—centered means you’re on the proper descent; above the glide path means you need to descend, below means you need to level off or descend less. Ground speed, gyroscopic stabilizer, and ground sensor refer to different concepts and aren’t the term represented by GS in air navigation.
