This class implements a NAV data decoder for GPS L1 C/A.
Class that contains all the configuration parameters for generic telemetry decoder block...
This class represents an interface to a telemetry decoder block.
This is the class that contains the information that is shared by the processing blocks.
Definition: gnss_synchro.h:38
This abstract class represents an interface to configuration parameters.
Interface of the Gnss_Satellite class.
This class represents a GNSS satellite.
Interface of a NAV message demodulator block based on Kay Borre book MATLAB-based GPS receiver...
This abstract class represents an interface to a navigation GNSS block.
std::string implementation() override
Returns "GPS_L1_CA_Telemetry_Decoder".
Interface of the Gnss_Synchro class.
