* \file galileo_e1_pcps_ambiguous_acquisition_gsoc_test.cc
* \brief This class implements an acquisition test for
* GalileoE1PcpsAmbiguousAcquisition class based on GSoC 2012 experiments.
*
* This test is a part of an experiment performed by Luis Esteve in the
* framework of the Google Summer of Code (GSoC) 2012, with the collaboration
* of Javier Arribas and Carles Fernández, related to the extension of GNSS-SDR
* to Galileo. The objective is perform a positive acquisition of in-orbit
* Galileo signals in the E1 band.
*
* Report:
