摘要
对伪卫星技术的原理、特点作了介绍,并结合小东江大坝监测实例,采用伪卫星技术,提高了GPS定位精度.结果表明,伪卫星能够显著增强几何图形结构,提升测量精度,尤其是垂直方向上的精度.
An introduction is given to the theory and characteristics of the pseudolite technique. The combination of the technique with GPS in the monitoring of the Xiaodongjiang Dam shows that the pseudolite technique greatly intensifies the structures of geometric figures and improves the precision of positioning, especially in the vertical direction.
