Morphology

uplink = link (semi-transparent) = up + link

The form clearly combines 'up' and 'link', but the specialized satellite-communications sense is not fully predictable for an average learner.

Etymology

Uplink is a simple compound of up and link. Up means 'towards the sky' and link means 'a connection', so an uplink is the connection used to send signals up to a satellite.
