Abstract: Disclosed are various embodiments of global navigation system tracking and decoding. In one embodiment a method includes obtaining a navigation signal including a sequence of navigation strings. Each navigation string includes symbol encoded navigation data symbols and a time mark sequence (TMS). A location of a TMS within the navigation signal is determined and the TMS and the symbol encoding is removed from a subsequent navigation string based upon the determined location of the TMS to provide a stripped navigation signal. In another embodiment, a global navigation receiver includes a RF front end that obtains a navigation signal including a sequence of navigation strings. The global navigation receiver determines a location of a TMS within the navigation signal and removes the TMS and symbol encoding from a subsequent navigation string based upon the determined location of the TMS to provide a stripped navigation signal.
