摘要
提出了用户端自主完好性监测可靠性评估方法。充分考虑所需导航性能参数和不确定噪声的因素,提出了基于概率极限状态模型的导航系统完好性二元指标体系及评价准则。即将安全系数与可靠系数相结合,建立导航系统完好性二元指标体系,给出了评估系统完好性监测的可靠系数。其次,阐述了二元指标体系评价准则,该算法可用于完好性监测,计算高效。非精密进近的仿真结果已用来证明该方法的有效性。
This paper proposes a reliability assessment method for Receiver Autonomous Integ- rity Monitoring（RAIM）.Probability limit state model offers tools for fault detection with the consideration of the Required Navigation Performance （RNP） parameter and uncertainty noise, while navigation system integrity by dual index system is established by safe coefficient com- bined with reliability coefficient and reliability coefficient is given to evaluate the system integ- rity.The dual index system evaluation criteria, which can be used to monitor the system integ- rity efficiently, is described.Simulation for Non-Precision Approach （NPA） validates both the viability and the effectiveness of the proposed method.
