上面的FIX中我们可以看到，本次定位的PN LOOK UP 成功率相当低，定位方式是Mixed Cell，虽然HEPE 值较好，但实际上都是定位在了SRV_BS所在扇区的扇区中心，实际定位精度并不高。在这次定位中有9个PN评分很低，PN LOOK UP 失败，这些PN的Pphase都很差。但是我们仔细分析文件，不难发现PN 39，12，384，345的MAR都设的比较小，在fix文件中都小于相应的RNG，因此我们试着调大这些扇区的MAR，其中PN12的MAR从500增到1500，PN384的MAR从1500增到2000，PN39的MAR从500增到1500，PN345的MAR从500增到1500。并进行再一次的测试，接下来再看复测的FIX文件。
