Abstract
In a method and apparatus for processing a received navigation signal x'(t) of a satellite navigation system, the received navigation signal x′(t) contains at least four navigation codes. The navigation codes are modulated by a complex BOC signal and a defined subcarrier frequency such that the resulting signal has a constant amplitude. The resulting signal is then also modulated by means of a carrier signal. The navigation signal x′(t) is demodulated and then processed by a complex correlation with at least one reference signal.
