 Global Navigation Satellite Systems receiver defined by software.
 It performs all the signal processing from raw signal samples up to the
 computation of the Position-Velocity-Time solution, including
 code and phase observables. It is able to work with raw data files or, 
 if there is computational power enough, in real time with suitable 
 radio frequency front-ends. This software is mainly developed at CTTC 
 (Centre Tecnologic de Telecomunicacions de Catalunya, http://www.cttc.es) 
 with contributions from around the world.
