# Why is Morse code used in satellite communication compared to ASCII encoding

My knowledge about methods of transmission of data is limited, but I believe that communication between transmitters and receivers often uses Morse code to send information.

If say, a satellite wanted to send a message consisting of letters from the English Alphabet, wouldn't it be possible to send it via either Morse, or ASCII, i.e., 'A' may be sent as .- (which may then be translated to the most appropriate form to be transmitted over an EM Wave) or as 01000001?

Is there any reason why Morse is preferred?

• The premise of your question is false. Morse code is not used to communicate with satellites. – brhans Sep 4 '18 at 12:25
• Though there may be a very distant similarity. The data is compressed, often using Huffman or similar algorithms: the most frequently repeating fragments are replaced with the compression shortest tokens. Morse Code was a precursor to this compression, assigning the shortest codes to most frequently used letters. ('E' is a . T is -. A is .-. N is -.. Rarely used letters get lengthy codes, like Q: --.- ) That might have been the source of the confusion. – SF. Oct 5 '18 at 13:54
