Abstract

Airports Authority of India (AAI) in collaboration with Indian Space Research Organization (ISRO) has planned to demonstrate Wide Area Differential GPS (WADGPS), over the Indian Flight Information Region for civil aviation application purpose. In GAGAN-TDS (GPS Aided Geo Augmented Navigation-Technology Demonstration System), with a configuration of eight Reference Stations, one Indian Master Control Station, one Indian Land Uplink station with one GEO stationary satellite, accuracy and availability of GAGAN was demonstrated. GAGAN-TDS is leading to a Fully Operational Phase (FOP) Indian SBAS (Space Based Augmentation System). GAGAN will operationally provide Accuracy, Integrity, Continuity, Availability and level of Service.

印度地区GAGAN SBAS(广域差分GPS)实时定位精度和LNAV/VNAV服务可用性评估
印度机场管理局(AAI)与印度空间研究组织(ISRO)合作,计划在印度飞行情报区演示广域差分GPS (WADGPS),用于民用航空应用。在GAGAN- tds (GPS辅助地理增强导航技术演示系统)中,以8个参考站、1个印度主控站、1个印度陆地上行站和1颗Geo静止卫星为配置,验证了GAGAN的精度和可用性。GAGAN-TDS是印度SBAS(天基增强系统)全面运行阶段的先导。GAGAN将在操作上提供准确性、完整性、连续性、可用性和服务水平。
