摘要
分析了北斗卫星导航系统数据模型,并通过实际案例测试了其动态服务精度。结果表明,区域北斗地基增强系统的动态服务精度指标完全达到了相关标准的要求,特别是BDS+GPS组合较之传统GPS增强系统有较大的提升,体现了多系统融合的优势,也为北斗卫星导航系统在相关领域的推广应用提供了丰富的数据支撑。
In this paper, the data model of BeiD ou Navigation Satellite System(BDS) was analyzed, and the precision of dynamic service was tested by practical cases. The results show that the precision indexes of dynamic service of regional BeiD ou ground-based augmentation system completely satisfy the requirements of relevant standards. Especially compared with traditional GPS augmentation system, the combination of BDS+GPS has larger advantages, which presents the advantage of multi-system integration and offers abundant data supports for the promotion and application of BDS in relevant fields.
