In the Galileo system, as in the modernized civil GPS, there are two-channel
navigation signals including a data channel, carrying navigation
data, and a pilot channel. This work addresses the problem of cold
acquisition of weak two-channel navigation signals in a software
receiver. It addresses the cold acquisition of two-channel navigation
signals. Different approaches, with and without channels combination,
and with coherent and non-coherent combination of primary code integrations,
are analyzed, simulated and compared with alternative solutions.
