摘要
利用GPS定位技术建立各种用途控制网已经相当普及。针对GPS控制网建立前观测方案的优化设计进行研究,探讨接收机的适用条件以及GPS观测时间的确定。实验数据证明接收机的选择和观测时间的确定对控制网控制质量是很重要的,实验分析结果既可为GPS科研工作的深入研究提供参考,亦可为从事高精度GPS测量生产应用提供借鉴。
It has been widely used for the GPS technology in various purposes survey control network.The paper aims at the optimal design of GPS observation scheme before GPS control network should be carried out,and the focus is on two issues including GPS observation time and receiver working conditions.The testing data shows that it is important to choose observation time and GPS receiver for the network quality control.The result of GPS relating testing could be helpful for both GPS in-depth study and GPS high-precision applications.
