GNSS Receiver

The GNSS receiver is primarily used to receive GPS-L1 and BD2-B1 dual-mode navigation signals. It provides orbit determination, positioning, and timing data for the entire satellite. According to the mission requirements, it uses dual-antenna combined positioning and has an on-orbit lifespan of 3 years.
