Аннотация
The work presented in this paper introduces an innovative architecture
for the tracking loop within the Galileo receiver (i.e. an innovative
Delay Lock Loop (DLL)) which has been patented by the authors 1.
Such an innovative strategy has been especially tailored for the
alignment of a Binary Offset Carrier (n.n) (BOC) modulated signal.
It is in fact well known that BOC(1,1) has been chosen as the format
of the Signal-In-Space (SIS) broadcast by the novel European satellite
navigation system Galileo for the Open Access Service (OAS) over
the L1 carrier frequency 2. The innovative internal architecture
here proposed is able to exploit all the features of the BOC(1,1)
signal reducing the overall complexity of the required hardware and
software blocks. Such an architecture applies to all BOC(n.n) possible
signals.
