摘要：

通过对单频接收机的“虚拟多频点”电离层延时关联模型的研究，建立了一种新型单频接收机虚拟多频接收机自主完好性监测方法，给出了虚拟多频故障监测和识别的判据．仿真结果表明，“虚拟多频”接收机自主完好性监测方法不仅突破了传统接收机自主完好性监测算法对可见星数目的限制，而且还能在不改变单频接收机硬件结构的前提下，极大地提升接收机的完好性监测性能，具有很好的理论意义和实用价值．

Abstract:

In the GNSS era, how to effectively enhance the navigation signal integrity monitoring capacity by using multi-frequency information is becoming a hot topic and the mainstream of RAIM technique. Based on the “virtual” multi-frequency ionospheric delay model of the single-frequency receiver, the paper proposes a novel virtual multi-frequency integrity monitoring technique for the single-frequency receiver, then presents the virtual multi-frequency criterion for fault detection and identification. Simulating results show that the “virtual multi-frequency” RAIM technique not only breaks through the limit to the number of visible satellites of traditional RAIM algorithms, but also greatly enhances the RAIM performance of the receiver without changing the hardware structure of the receiver, which would be of a tempting theoretical and practical value.

Key words: global navigation satellite system, receiver autonomous integrity monitoring (RAIM), virtual frequency techniques, parity vector method
