针对传统的基于最大似然法的距离域多参考一致性检验（MRCC）方法在满足CAT II/III完整性要求方面的局限性，提出了一种基于卡尔曼滤波的位置域方法，用于局域增强系统MRCC过程中的故障检测和排除。在本文中开发的位置域方法，旨在解决基于范围域的MRCC的局限性，不仅专注于提高性能的故障检测，但也对完整性的风险要求MRCC。此外，卡尔曼滤波器的位置域方法的稳定性的问题被认为是。在主站处，利用自适应卡尔曼滤波器对多个参考接收机的GPS距离改正进行融合，以检测和排除单个参考接收机的故障。已开发的卡尔曼滤波器为基础的MRCC的性能进行了比较与传统的方法使用实验数据。结果表明，在无故障情况下，传统方法的垂直保护水平略好于基于卡尔曼滤波的方法。在单故障情况下，相对于传统方法，该方法的可用性可提高到97%以上。在单故障情况下，即使考虑不同故障类型，定位精度也能提高32%以上。特别地，该算法可以是作为传统MRCC的可扩充补充的候选选项，并且可以在LAAS完整性监视架构的主站元件中实现。
Since the traditional Maximum Likelihood-based range domain multiple reference consistency check (MRCC) has limitations in satisfying the integrity requirement of CAT II/III for civil aviation, a Kalman filter-based position domain method has been developed for fault detection and exclusion in the Local Area Augmentation System MRCC process. The position domain method developed in this paper seeks to address the limitations of range domain-based MRCC by focusing not only on improving the performance of the fault detection but also on the integrity risk requirement for MRCC. In addition, the issue of the stability of the Kalman filter in relation to the position domain approach is considered. GPS range corrections from multiple reference receivers are fused by the adaptive Kalman filter at the master station for detecting and excluding the single reference receiver’ failure. The performance of the developed Kalman filter-based MRCC has been compared with the traditional method using experimental data. The results reveal that the vertical protection level is slightly better in the traditional method compared with the developed Kalman filter-based approach under the fault-free case. However, the availability can be improved to over 97% in the proposed method relative to the traditional method under the single-fault case. Furthermore, the fault-tolerant positioning result with an accuracy improvement of more than 32% can be achieved even if different fault types are considered under the single-fault case. In particular, the algorithm can be a candidate option as an augmentable complement for the traditional MRCC and can be implemented in a master station element of the LAAS integrity monitoring architecture.
