The Red Hat (RH) Network (RHN) Satellite server is a management tool developed by Red Hat Inc. to assist with the monitoring of specific alarms and the updating of Red Hat Enterprise Linux (RHEL) server farms.

Each server being administered by a satellite must first be registered on the satellite server and assigned to a software channel and organization.
