摘要
讨论利用GPS-RTK的作业模式,采用超快速静态建立GPS控制网的新方法。将常规的RTK方法中参考站固定不动改变为参考站和流动站交替流动,每时段至少获得一条独立的基线向量,所有的基线按设计的网形组成多边形GPS网,网的各项指标执行城市GPS规范,数据按静态网的数据处理方法进行。实践结果表明,该方法获得的结果可靠,具有速度快、效率高、操作简便等特点,能达到城市GPS规范各等级的精度要求。
This paper discusses a new method that using ultra-fast speed static GPS to establish control network in GPS-RTK operation mode. This method change the fixed reference stations in conventional RTK method to the turn of the mobile stations and mobile stations, each time acquiring at least an independent baseline vector; all of the baseline compose a polygon-shaped GPS network in accordance with design; the precision of the GPS network can be strictly in line with the urban GPS measurement norms, GPS network data-processing in accordance with static GPS data processing methods. Practice results show that the the result of method was reliable, fast, efficient, easy to operate and so on, and it can be in line with the urban GPS measurement norms.
