【摘要】：為研究GBAS參考接收機(jī)精度對多參考接收機(jī)一致性影響,通過理論推導(dǎo)和仿真驗(yàn)證,建立參考接收機(jī)定位精度與多參考接收機(jī)一致性(B值)之間的關(guān)系。通過接收機(jī)數(shù)據(jù)采集實(shí)驗(yàn),并依據(jù)上述理論對GNSS參考接收機(jī)偽距等原始觀測數(shù)據(jù)進(jìn)行處理以及作圖分析。實(shí)驗(yàn)結(jié)果發(fā)現(xiàn)隨著定位精度提高B值變小,即參考接收機(jī)一致性提高。在此基礎(chǔ)上給出了一般情況下,滿足連續(xù)性要求的地基增強(qiáng)系統(tǒng)(GBAS)參考接收機(jī)水平定位精度應(yīng)在0.1 m左右(即分米級)。該實(shí)驗(yàn)結(jié)果可在GBAS試驗(yàn)時(shí)為參考接收機(jī)選取提供參考。
[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.
