接收机天线相位中心改正对IGS/IGMAS站的影响
|
摘要
针对天线相位中心改正影响GPS数据解算以及处理软件不能识别接收机天线类型的问题,该文提出了利用近似型号的天线进行数据处理的方法。首先利用IGS站精确确定天线相位中心改正对数据解算造成的影响,再利用IGMAS站验证方法的可靠性。该文选取部分IGS、IGMAS站的数据,利用GAMIT软件进行试验并分析。结果表明,当不使用天线相位改正模型时,增大了单天基线解的NRM_S值,并增加15.5%的基线误差,对精密定位能带来平均2cm的影响;当将处理软件不识别的天线换成近似能识别的天线时,基线解效果要比不使用天线改正效果好,水平和垂向的定位精度均在3.9mm左右,比使用原装能识别天线的定位精度稍差。该方法既保证了精度,也较为简单快捷。
For the problem that the antenna phase center correction could affect the resolving of GPS data,and the example of the software can't identify the receiver antenna type,a method which used an approximate antenna to replace the unidentified antenna when data processing was proposed.The effect of antenna phase center correction on the data resolving was determined by using the IGS stations accurately,and reliability of the method was checked by using the IGMAS stations.Part of the IGS,IGMAS station data were used to test and analysis by using software which named GAMIT.The results showed that the NRM_S value of the single-day baseline solution was increased when not using the antenna phase correction model,and the baseline error was increased by 15.5%,it's also showed that the antenna phase center correction had effect on the precision positioning about 2 cm;When the unrecognized antenna was replaced with an approximately recognizable antenna in software,the accuracy of baseline solution was better than that without the antenna correction's,and the horizontal and vertical positioning accuracy was about 3.9 mm,but it's slightly lower than that with the original antenna type's.Generally,this method can not only ensure accuracy,but also be simple and quick relatively.
