An approach of CBOC signal tracking based on pseudo correlation function

In consideration of the construction of the next generation Global navigation satellite system and the high requirement of sensitivity and multipath mitigation, a way of the code tracking which was to construct a pseudo correlation function (PCF) was designed, and the tracking strategy was produced so as to improve the performance of multipath mitigation and promote sensitivity based on the Galileo E1 open service CBOC signal. According to the study results of the bandwidth-limited performance of multipath mitigation and the sensitivity, it is concluded that the new method ameliorates the multipath mitigation and sensitivity of the CBOC signal tracking loop.
