Expanding the receiver to BEIDOU B1C

The current version of GNSS-SDR supports GPS, GALILEO, GLONASS and BeiDou Global Navigation Satellite System signals. Right now in BeiDou signals, GNSS-SDR fully supports BeiDou B1l and BeiDou B3I. The primary goal of this project is to make the software receiver compatible with the BEIDOU B1C signals. This project will enhance the software receiver to aid acquisition and tracking of BEIDOU B1C signals that would further expand the receiver's capabilities and would facilitate research on multi-constellation, multi-frequency receiver working with real signals. The demodulation of the B-CNAV1 navigation message of BEIDOU B1C will open the door to innovation in multi-constellation receivers. Along with the fully functional implementation of a GNSS receiver working with BEIDOU B1C signals, this project will help to address topics such as integrity, reliability, robustness, enhanced coverage, and high-accuracy positioning. Additionally, the integration of BEIDOU B1C observables into the position, velocity, time (PVT) solutions will allow the achievement in a diverse range of applications and components.
