A "Gold code" typically refers to a special type of pseudorandom binary sequence used in telecommunications (like GPS and CDMA) for efficient channel identification, known for low interference. Less commonly, it can mean the final, stable software release version (the "gold master") or a secret authentication sequence for US military launch orders, but the primary technical meaning relates to these unique sequences for spreading spectrum systems.
