最近,美国一家GPS公司制造了一种GPS接收设备,在满足卫星测量的条件下,它能确定实时(1s)、高精度(20mm)的三维坐标。 采用这种新的实时移动GPS设备,可望直接找到目标点。也可望使建筑管理人员更经常地实施地形观测。这些观测为他们提供了很重要的土方开挖量和填方量的信息。他们得到这些信息,可保证建筑作业更经济、更有效。如果实时移 Recently, a GPS company in the United States created a GPS receiver that determines three-dimensional coordinates in real-time (1s) and high-precision (20mm) under satellite measurements. With this new real-time mobile GPS device, it is expected to find the target directly. It is also expected that construction managers will be able to implement more frequent terrain observations. These observations provide them with important information on earth excavation and fill volume. They get this information to make construction more economical and effective. If you move in real time
