Abstract:
The present invention relates to a code tracking technology and, more specifically to, a code tracking system and a code tracking method of a multiplexed binary offset carrier signal which is a representative civil positioning signal of a global navigation satellite system. According to the present invention, provided is a code tracking system which reduces the ambiguity of a code tracker by using one multiplexed binary offset despreader and one binary offset carrier despreader, in contrast as a conventional code synchronization tracker for a multiplexed binary offset carrier signal uses a multiplexed binary offset carrier despreader only, and thus false lock point can be reduced remarkably within one chip based on an accurate synchronization point of time basis.
