I am not deploying satellite into the space at the moment..but i just want to listen to the other cubesat/nanosats or LEOs that are there in the space..dont want to communicate or send/recieve any data..at that point of time do we really need a one? thats my question..hope i have made it clear
can we go for a made one? or can we assemble one..so that we can minimise the total cost? any details about kenwood TS-2000 transceiver or anyother available ones in market ?
Depending on type of communication, in many cases is a simple receiver enough if you have a antenna with high gain. For weather satellites can you buy cheap receiver kits which connects to PC sound-card.
High antenna gain => narrow lobe => Tracking helps to keep contact a bit longer time.
Many LEO satellites communicate in a narrow band mode and is moving in high and very variable speed relative base station => Receiver needs to track center frequency due to Doppler-effect.
