摘要:

为了提供准确可靠的完好性服务,提出了基于概率极限状态的RAIM完好性风险评估。考虑所需导航性能参数和噪声的因素,建立了安全系数与可靠系数相结合的完好性风险评估指标体系,确立风险评价准则。非精密进近的算例分析表明,系统评估方法是可行的且有效的。

Abstract:

In order to provide accurate and reliable integrity service,the integrity risk assessment for receiver autonomous integrity monitoring based on probability limit state is proposed. Taking into account the required navigation performance parameters and noise factors,the system indices of the integrity risk assessment are established combining with the safety factor and reliability coefficient. And then,the evaluation criterion is established for the integrity risk assessment of receiver autonomous integrity monitoring reliability. Simulation for non-precision approach validates both feasibility and effectiveness of the proposed algorithm.

Key words: receiver autonomous integrity monitoring, probability limit state, required navigation performance, nonprecision approach, missed detection probability
