有机高分子材料对GNSS测量系统性能的影响分析

Influence Analysis of Organic Polymer Material on the Performance of GNSS Measurement System

通过初选和扩大实验两个步骤,使用聚乙烯薄膜(简称PE薄膜)和天然乳胶薄膜(简称乳胶薄膜)这两种有机高分子材料,对不同型号GNSS测量系统进行包覆,并按照相关检定规程提供的检定方法对包覆后仪器进行性能检测,测试PE薄膜和乳胶薄膜对GNSS测量系统的卫星信号接收能力、天线相位中心一致性,并对测量精度和散热情况进行了分析对比,评价两种材料对GNSS测量系统性能的影响。

In this paper,we used two organic polymeric materials,polyethylene film and natural emulsion film,in the primary election and the expansion test.We coated different types of GNSS measurement system at first,and tested the performance of coated instruments according to the verification methods provided by relevant verification regulations.Finally,we analyzed and compared the satellite signal receiving ability,phase center consistency,measurement accuracy and heat dissipation of the GNSS measurement system with PE film and latex film,and evaluated the influence of the two materials on the performance of the GNSS measurement system.
