L2C (L2 band Carrier) is the second Global Positioning System (GPS) civilian signal to become available over the full constellation. Because of the unusually-long ranging codes used in L2C signal, the search space and the computational complexity for signal acquisition become huge. Software-based GPS Receiver (SGR) helps the users processing the GPS signal at the lowest level of GPS raw signal data from the antenna. A software-based GPS receiver consists of a front-end device that converts the radio frequency signal from the antenna to an intermediate frequency in digital format.
