Feeder Link

ITU Radio Regulations define feeder link as follows:

A radio link from an earth station at a given location to a space station, or vice versa, conveying information for a space radiocommunication service other than for the fixed-satellite service. The given location may be at a specified fixed point, or at any fixed point within specified areas.

Thus, feeder link denotes the link between satellites and ground stations to convey information for a space radiocommunication.

The meaning of feeder is, according to the dictionary,

used to refer to something that leads to or supplies a larger thing of the same type

Thus, the feeder link should be used for other purposes.

For example, broadcasting satellite convey information from ground stations to the satellite.

This link from ground stations to the satellite is called feeder link (the link from the satellite to ground stations are called service link).
