The [[Compact Disc]] and [[Voyager Program]] spacecraft use concatenated error correction technologies. Concatenated error codes may have been introduced with spacecraft missions that were involved with mapping the Moon and Mars{{cnFact|date=July 2008}}. In typical telecommunications systems before these data intensive missions -- only one hard error correction layer was used.

Concatenating [[error correction]] methods is useful in cases where the telecommunications link may be problematical. Typically a soft inner code (Viterbi) is used concatenated to a hard outer code (Reed-Solomon).
