Satellite Communication : Link Design: Power Level Diagram Power Level Diagram

Satellite Link Design Transmission Losses :The difference between the power sent at one end and received at the receiving station is known as Transmission losses. The losses can be categorized as 1. Path Loss 2. Atmospheric Loss 3. Losses Associated with Transmitter a. Antenna De-Pointing Loss b. Feeder Loss 4. Losses Associated with Receiver a. Antenna De-Pointing Loss b. Feeder Loss c. Polarization Loss

Satellite Link Budget

Satellite Communication: Link Designs Tutorial Q1. Find path loss for an UPlink operating at 6 gigahertz with the distance 42000 kilometre if earth station EIRP is 120 dBW and antenna gain is 20 dB then what will be the received power in dBm Q2. A satellite at a distance of 40000 kilometre from a point on the earth surface radiates a power of 10 watt from an antenna with a gain of 17 dB  in the direction of observer. find the flux density at the receiving. And the power received by an antenna at this point with an effective area of 10 metre square Q3. Find the received power for given satellite specification: Satellite distance =40000 kilometre  Transmitting antenna gain = 17 dB  Receiving antenna gain is = 52.3 dB  Radiated Power =10 what  Operating frequency =11 gigahertz Atmospheric loss = 4dB  Losses associated with transmitter =8dB  Losses associated with receiver= 3dB
