High-precision navigation data are exceptionally vulnerable to channel fading, background noise, multipath interference, link delay, and packet loss within complex wireless communication applications. To address these critical challenges, the intricate coupling between communication channel optimization and robust navigation data processing is comprehensively considered in this study. Based on the fundamental principles of navigation data transmission and the mechanisms of channel degradation, a novel channel state awareness and data fusion processing framework tailored for high-precision navigation applications is systematically developed. Within this proposed framework, key performance indicators, including the signal-to-noise ratio (SNR), bit error rate (BER), packet loss rate (PLR), and transmission delay, are considered as primary observations to fully evaluate the reliability of the communication link. Subsequently, the channel quality evaluation results are seamlessly integrated into navigation data preprocessing, anomaly detection, dynamic weight allocation, and error feedback correction mechanisms. To validate the proposed methodology, five distinct simulation scenarios—encompassing normal channel conditions, low SNR, multipath effects, high packet loss, and dynamic occlusion—are rigorously tested. These simulation scenarios are quantitatively compared with traditional Kalman filtering, weighted least squares, and ordinary multi-source fusion techniques. The results demonstrate that the navigation data processor, when constrained by channel optimization limits, can significantly decrease the mean positioning error in a complex environment. Furthermore, it substantially improves overall data accuracy and trajectory continuity. Ultimately, this research provides substantial engineering reference value for civil aviation navigation data links, airport surface movement guidance, airborne GNSS/INS integrated navigation, and BeiDou/GNSS-based high-precision aviation terminals.References
