【摘要】:为研究GBAS参考接收机精度对多参考接收机一致性影响,通过理论推导和仿真验证,建立参考接收机定位精度与多参考接收机一致性(B值)之间的关系。通过接收机数据采集实验,并依据上述理论对GNSS参考接收机伪距等原始观测数据进行处理以及作图分析。实验结果发现随着定位精度提高B值变小,即参考接收机一致性提高。在此基础上给出了一般情况下,满足连续性要求的地基增强系统(GBAS)参考接收机水平定位精度应在0.1 m左右(即分米级)。该实验结果可在GBAS试验时为参考接收机选取提供参考。
[Abstract]:In order to study the effect of the precision of GBAS reference receiver on the consistency of multi-reference receiver, the theoretical derivation and simulation are carried out. The relationship between the positioning accuracy of the reference receiver and the consistency B value of the multi-reference receiver is established. The data acquisition experiment of the receiver is carried out. According to the above theory, the original observation data such as pseudo-range of GNSS reference receiver are processed and analyzed. The experimental results show that the B value becomes smaller with the increase of positioning accuracy. That is, the consistency of the reference receiver is improved. On this basis, the general situation is given. The horizontal positioning accuracy of the GBAS-based reference receiver should be about 0.1 m (that is, the decimeter level), which meets the requirement of continuity. The experimental results can be used as a reference for the selection of reference receivers in GBAS experiments.
