 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 
 radiofrequency 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.
