Uplink
An uplink is the communication path from a ground station on Earth to a spacecraft in space. It's how commands and data are sent to the satellite.
TECHNICAL DEFINITION
Uplink refers to the radio frequency communication link transmitting data, commands, and software updates from a ground station or another space asset to a spacecraft, enabling command and control functions.
