<p>A method and apparatus for improving speed of acquisition of spread spectrum signals in a satellite navigation system. The method includes receiving signals including the spread spectrum signal having a first spreading code; performing a correlation between the received signals and a composite code, the composite code including a superposition of the first spreading code and a second spreading code; detecting a plurality of peaks of the correlation; identifying at least one of the plurality of peaks that relates to the spread spectrum signal; and detecting the spread spectrum signal based on the at least one identified peak.</p> |
