The traditional satellite navigation receiver with multi antennas forming long baselines is based on carrier phase difference measurement for DF (Direction Finding). It has many problems, such as cumbersome baseline calibration, complex phase ambiguity removing algorithm and high application cost. A new satellite navigation receiver with three antennas amplitude comparison DF based on baseband information fusion is designed in this paper. Its working principle, parameter optimization, and solution to DF are described in detail. Through associated baseband information, the parameters guidance for each channel to receive the navigation signal is realized for rapid acquisition and tracking. DF is completed by measuring the carrier to noise power ratio of signals from different antennas for the same navigation satellite. Finally, a prototype system is developed by using the commercial satellite navigation receiving antennas, and experiments are carried out for the actual navigation signals to verify the effectiveness of the design. This kind of receiver not only has many uses, such as attitude measurement, DF for navigation signals, and anti-deception based on DF information, but also shows many advantages, such as high antenna integration, small installation spaces, convenient use and high performance. So it will have wide application in the future.
