Deep-space Telecommunications

Posted in | 02.25

Many modern modems have their origin in dees space telecommunication systems of the 1960s.

Differences with deep space telecom modems vs landline modems

  • digital modulation formats that have high doppler immunity are typically used
  • waveform complexity tends to be low, typically binary phase shift keying
  • error correction varies mission to mission, but is typically much stronger than most landline modems
