In recent years, Beidou-2 satellite navigation receiver has been widely used in military and civilian fields. With continuous development and improvement of Beidou-3 satellite navigation system, the development of the Beidou-3 single-mode multi-frequency satellite navigation receiver has become one of the important research directions in the field of Beidou satellite navigation. Combining the characteristic of satellite signal at various frequency points in Beidou-3 navigation system, from the perceptive of engineering practical application, a Beidou-3 single-mode multi-frequency satellite navigation receiver architecture was designed and studied based on field-programmable grate array (FPGA)+dignal signal processing (DSP). By designig the overall architecture of the receiver, the mechanisms of the radio frequency module for satellite signal at the different frequencies, the baseband signal acquisition and tracking module, and navigation positioning calculation module was elaborated in detailed. At the same time, the corresponding hardware driver circuits of the Beidou-3 satellite navigation receiver was designed. Finally, the feasibility of the designed scheme was verified by setting static and high dynamic positioning scenairos on satellite navigation signal simulator. The experimental results show that the receiver designed and implemented can meet the technical specification requirements, further verifying the effectiveness of the proposed scheme.
