Satellite Uplink And Downlink Design

The communication going from a satellite to ground is called downlink and when it is going from ground to a satellite it is called uplink.

Satellite uplink and downlink design.

This chapter describes how the link power budget calculations are made. Satellite communication module 3 satellite link design 02 11 14 2 3. W e set up the satellite based infrastructure which allows smooth always on connectivity. Satellite downlink in this process satellite sends the signal and the earth station receives it.

What are uplink and downlink. We enable the power of the internet. Communication satellites bring the world to you anywhere and any time. This block determines the type of transponder.

The cost of transmitters tend to be high compared with the cost of receiving. When an uplink is being received by the spacecraft at the same time a downlink is being received by earth the communication is called two way. The term uplink chain is used to refer to the series of pieces of equipment that are used to produce a radio frequency signal for sending out data. It receives uplink signal from the satellite antenna and transmits downlink signal to the satellite antenna.

These calculations basically relate two quantities the transmit power and the receive power and show in detail how the difference between these two powers is accounted for. We design build commission and maintain satellite uplink downlink systems on a turnkey basis. Low noise amplifier lna amplifies the weak received signal. The uplink dish is pointed toward a particular satellite and the uplinked signals are transmitted within a specific frequency range so as to be received by one of the transponders tuned to that.

Uplink downlink intersatellite links relay satellite relay satellite relay satellite sensor satellite sensor satellite crossover or intersatellite links mission data launch phase tt c tt c satellite ground station tt c tracking telemetry and control the communications architecture consists of satellites and ground stations interconnected with. Universal engineering college thrissur 680123 department of ece ec09 l05. The description provided here is imprecise as the exact configuration can vary widely. Carrier processor performs the frequency down conversion of received signal uplink.

Satellite uplink and downlink analysis and design. Take a look at the drawing below and note the path of devices on the left hand. Design of the satellite link 1.
