How will you distinguish a uplink frequency from downlink frequency?

The uplink frequency is the frequency which is used for transmission of signals from earth station transmitter to the satellite. The downlink frequency is the frequency which is used for transmission of signals from the satellite to the earth station receiver.

Why the uplink and downlink frequencies are different in a satellite?

In satellite communication, the uplink frequency is higher than the downlink frequency because the attenuation level increase with an increase in frequency. The power at the ground station (Base Station) is more than compared to the power available at the satellite.

What is the difference between uplink and downlink?

In satellite telecommunication, a downlink is the link from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground station up to a satellite. Some companies sell uplink and downlink services to television stations, corporations, and to other telecommunication carriers.

What is beacon frequency in satellite?

Satellite beacons used for ionospheric research normally transmit in the VHF (30-300 MHz) or UHF (300 – 3000 MHz) bands.

What is the uplink and downlink frequency?

The frequency with which, the signal is sent into the space is called as Uplink frequency. Similarly, the frequency with which, the signal is sent by the transponder is called as Downlink frequency. Uplink frequency is the frequency at which, the first earth station is communicating with satellite.

What is a beacon compared to a radio beacon?

In navigation, a radio beacon (rarely electromagnetic beacon) is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. Occasionally, the beacon’s transmission includes other information, such as telemetric or meteorological data.
