| 摘 要： | 基于GPS数据处理的TEQC软件,对威宁GPS站在2011年8月5日-2012年10月15日期间的观测数据进行了质量分析.得出威宁GPS地面接收机接收到的数据比较平稳,周跳较少.接收机在接收L1和L2频率波段时对外界其他信号的抵抗能力也较强,但是实际采集的数据远远少于应采集的数据量,通过对比威宁站和其他6个IGS观测站在同一时段观测到的卫星个数,得出威宁站GPS地面接收机在每个时段跟踪到的卫星个数很少,少于3个卫星的时段所占比例较高,从而导致数据利用率较低. |
| 关 键 词： | TEQC软件 GPS数据质量 观测卫星个数 |

| Abstract: | This article using TEQC which is commonly used in GPS data translation,editing,and quality checking. Checking time from August 5,2011 to October 15,2012. Finally find out that the data of Weining GPS ground receiver is relatively stable,less jump. The resistance ability is strong when the receiver in receiving L1 and L2. but the actual collection of data is far less than the amount of data to be collected. So this article choose 6 other IGS stations to compare the observed satellite number. The results as follows：The number of satellite which got by Weining GPS ground receiver in each period is little,less than 3 satellite most time,which leads to low data utilization rate. |
