摘要
Abstract
For LPV-200 approach service, the definition of integrity failure is substantially more stringent than for conventional RAIM schemes that have been used to provide integrity for lateral navigation (LNAV). Advanced RAIM (ARAIM) algorithm internationally has begun to rise recent years and demonstrated its superiority due to the ability of vertical navigation. Moreover, optimized allocation of the probability of hazardous misleading information is able to further reduce VPL as well as improve the availability. By using Spirent GSS 8000 satellite navigation simulator to set a scenario for LPV-200 and generate corresponding data, the simulation of ARAIM after optimization is compared with that of prior to optimization. The results optimistically indicate that it is conceivable to achieve LPV-200 service with the help of dual-frequency GPS in localized areas.关键词
