By means of decrease in differential reference stations and the communication with mobile gps , we will realize the good economic goal what include gps construction cost of navigation system and operate cost 在减少差分基准站和差分信号传输链路硬件系统的条件下,达到降低gps定位系统的建设成本和运行成本的经济目标。
Analyzing the characteristics of the time - series data of horizontal displacement from the continuous gps network in time and frequency domain , the similarity transformation is conducted in order to give prominence to the local deformation by selecting a few stations in the eastern china 摘要对gps基准站连续观测水平位移时间序列数据的时频特征进行了分析,为了突出局部变化的信息,在中国大陆东部选取一组参考点进行相似变换。
The results obtained from the simulation example suggest a good effect and significance of using gps simulation data for demonstrating the feasibility and validity of an od design or an algorithm of certain problem . 4 the ill - conditioned problem existing in relative kinematic od using gps carrier - phase data is discussed and then some preliminary efficient approaches for solving this problem are given out there are several reasons that cause the ill - condition pro (四)探讨了星载gps相位相对定轨中的病态性问题,并尝试给出了较有效的解决方案地面基准站、低轨卫星和gps卫星之间的几何形状分布不佳,差分技术的应用使得模糊度之间及模糊度和三维坐标向量改正之间产生较强的相关性,往往都会导致星载gps定轨中的法矩阵的病态性。
Fully considering the system ' s reliabilty , being real - time , speed and extensibility , it finally chooses the sdh as the system network of cors through deep compration and alalysis of four special data lines supplied by china telecom , so that an effective interconnection among the stations and the workstations in the control - center comes true 摘要充分考虑系统可靠性、实时性、通信速率、可扩充性等因素,通过对中国电信提供的4种数据专线服务的综合分析比较,选择了同步数字体系作为系统通信网络,实现了控制中心各工作站和各基准站之间的高速互联。
