Uplink
Uplink is a fundamental term in satellite communications that refers to the transmission of signals from Earth stations or ground equipment up to satellites in space. Think of it like a one-way street going up to the sky - it's how we send information to satellites. This is different from "downlink," which is when the satellite sends signals back to Earth. When you see this term in a resume, it usually indicates experience with ground station operations, satellite communications equipment, or managing satellite transmission systems.
