A Satellite signal transmitted from a satellite transponder to earth’s station is Downlink
Downlink refers to the transfer of a signal from a satellite to a second ground station through a channel. This signal is converted into a different frequency by the satellite transponder and sent down to the second earth station. Downlink frequency is the name given to this frequency.
The phrase "downlink" is used in radio and satellite communications to describe the link between the network and the end user, or between the satellite and the earth. It is a telecommunications link that transmits signals from a satellite, spacecraft, or aircraft to the ground. Downlink simply refers to the procedure by which a satellite beams information down to earthbound terminals or equipment in satellite communications. In computer networking, the phrase is used in the same way.
Downloading is the process of receiving data from the network core or higher-level network nodes such as routers and servers via edge terminals or nodes. As a result, photos and movies are downloaded using this method.
The phrases downstream and upstream are used to describe data flow from the network to the end-user and from the end-user to the network in fixed-line networks, respectively. The downlink frequency is the frequency utilized for signal transmission from the satellite to the ground station receiver. If both the uplink and downlink used the same frequency, the satellite transmitter creates a signal that would jam its own receiver.
Answer:
1. The transmission of a signal from the satellite to the second earth station through a channel is called a downlink.
2. The satellite transponder converts this signal into another frequency and sends it down to the second earth station.
3. This frequency is called Downlink frequency.
4. A transmitter-receiver subsystem onboard the satellite that processes, amplifies, and retransmits.
