Uplink and Downlink Segment

The uplink and the downlink are the terminologies that are used in the satellite communications. The data when sent from the ground to the satellite is called the uplink and data when sent from satellite to ground is called downlink. The uplink and the downlink process goes in parallel and this is also a two way communication.
