摘要
卫星高度角的大小是用户为获得GPS定位高精度结果需考虑的主要因素之一,介绍了TEQC软件的功能以及辅助软件QCVIEW 32和TEQCPLOT的绘图功能,提出了分别利用广播星历和精密星历计算卫星高度角的方法,给出了应用实例,讨论了利用TEQC计算卫星高度角的误差特点,结果表明:利用TEQC求得卫星高度角可以满足普通用户的精度要求。
The elevation of satellite is one of the main factors in order to get the high precision results by users. This paper introduces the powerful function of TEQC software and the plot function of QCVIEW32 and TEQCPLOT. The methods of calculating satellite＇ s elevation with broadcast ephemeris and precise ephemeris are described in detail. The examples of application were presented. Some research is made to analyze the error feature of elevation. The result indicates that the precision of elevation got from the broadcast ephemeris by TEQC can meet the common users＇ need.
