Abstract:
The present invention is related to location positioning systems, and more particularly, to a method and apparatus of synchronizing to data bits in a positioning system signal. According to a first aspect, the present invention speeds up data bit sync by allowing high Pfa in the overall bit sync computation (e.g. 10−2) for coarse aided case. According to another aspect, the present invention combines and aligns signals from satellites for use in the bit sync computation (e.g. for improved sensitivity and speed).
