Performance Analysis of BDS/GPS Single Frequency RTK Based on MLAMBDA Methodormalsize

  • 摘要: GNSS RTK技术以其高精度、高效率、实时性的优点,被广泛应用于航空航天等领域.目前双频RTK技术已非常成熟并且应用较广.相比于双频,单频GNSS RTK在数据质量控制、定位误差处理等方面存在难点.因此单频RTK服务精度可能会受到限制,其定位性能有待研究.本文基于扩展卡尔曼滤波模型,通过MLAMBDA模糊度搜索方法和Ratio检验法,结合实测数据,对比分析BDS,GPS,BDS/GPS三种模式下的单频RTK定位性能.实验证明在静态场景下,三种模式的单频RTK定位精度都在厘米级,可满足高精度定位需求;动态场景下三种模式的模糊度固定率都在70%以上,可满足日常定位需求.在静态及动态应用场景下,北斗的模糊度固定率最高,模糊度解算所用时间短,能实现快速RTK定位.
