| 摘 要： | 多径干扰信号会导致GNSS接收机伪距、载波相位和多普勒等测量精度降低,多径信号对GNSS接收机观测数据的影响与多径信号的延迟、幅度、相位等特性参数有关,造成的伪距测量误差高于载波相位测量误差2个数量级。多径抑制是GNSS接收机关键性能指标之一,GNSS接收机主要从试验室模拟环境和实际工作环境两方面检测多径抑制性能,多径误差包络检测技术利用模拟导航信号源完成多径抑制性能检测,码减载波和多径误差分析都是通过接收观测卫星导航信号并进行数据分析完成多径抑制性能的检测。

| Abstract: | Multipah results in the precision decrease of pseudorange,carrier phase and doppler of GNSS receiver.The magnitude of GNSS receiver's multipath error is based on the multipath's parameters such as delay,amplitude and phase,and the error of pseudorange is twice than carrier phase.Multipath mitigation is one of the key perfomance parameters for GNSS receiver.GNSS receiver's multipath mitigation performance can be detected under experimental analog simulation environments and GNSS satellite navigation signals ... |
