/*! * \file galileo_e1_pcps_ambiguous_acquisition_gsoc_test.cc * \brief This class implements an acquisition test 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. * * \author Luis Esteve, 2012. luis(at)epsilon-formacion.com * * * ------------------------------------------------------------------------- * * Copyright (C) 2010-2012 (see AUTHORS file for a list of contributors) * * GNSS-SDR is a software defined Global Navigation * Satellite Systems receiver * * This file is part of GNSS-SDR. * * GNSS-SDR is free software: you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation, either version 3 of the License, or * at your option) any later version. * * GNSS-SDR is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
