摘要
Method and apparatus for decoding a bitstream of navigation data broadcast by a satellite positioning system satellite is described. In one example, a portion of a subframe in the navigation data for each of a plurality of occurrences of the subframe in the bitstream is obtained at a satellite signal receiver to produce a respective plurality of subframe portions. The subframe portions are then combined to recover the subframe. The subframe portions may be processed to maintain a constant polarity by comparing a common sequence of data bits among at least two of the subframe portions to identify a mismatch in polarity.
