Abstract
In order to reduce the integrity risks and continuity risks in the process of precision vertical guidance of aircraft,and make the Receiver Autonomous Integrity Monitoring (RAIM) algorithm provide the horizontal and vertical integrity for security,this paper proposes a Multiple Hypothesis Separation Solution (MHSS)-based RAIM algorithm to solve Vertical Protection Level(VPL).The algorithm is based on the premise that the integrity and continuity of the Global NAvigation Satellite System (GNSS) can be met,and the optimal Vertical Protection Level(VPL) is obtained by optimizing the allocation of the integrity budgets and the continuity risks in each hypothesis failure mode.Simulation results show that the proposed algorithm can provide a more accurate VPL value and increase the availability of the system compared with the traditional slope-based RAIM algorithm.It also has good robustness with the increasing prior probability of satellite failure.关键词
