Abstract

Summary form only given. The authors describe a synergistic combination of existing systems in a novel way: a minimal-cost, minimum-risk, and maximum-gain solution to the integrity problem. The solution uses an innovative method of updating an INS (inertial navigation system) with GPS (Global Positioning System), and extends the amount of time available to the GPS operational control system (OCS) to detect an integrity failure, and act to remove the signal from service with a SATZAP capability. The authors first describe the combined system architecture for the aircraft GPS/INS navigation system as well as in the GPS OCS. The approach to evaluating the capabilities of the proposed system is then described.<>
GPS/INS协同解决方案对GPS完整性问题的评估
只提供摘要形式。作者以一种新颖的方式描述了现有系统的协同组合:对完整性问题的最小成本、最小风险和最大收益的解决方案。该解决方案采用了一种创新的方法,用GPS(全球定位系统)更新惯性导航系统,并延长了GPS操作控制系统(OCS)检测完整性故障的可用时间,并通过SATZAP功能将信号从服务中移除。首先介绍了飞机GPS/INS导航系统和GPS OCS的组合系统结构。然后描述了评估所提议系统的能力的方法。
