摘　　要：系统地探讨了导航型GPS观测参数测定的简易方法,并通过绝对定位精确度和相对定位精确度试验研究,发现导航型GPS定位中参数测定占主导地位,认为设置正确的观测参数是提高导航型GPS单点定位精度的重要途径。This paper has systematically discussed an easy way to determine observation parameters of navigation-based GPS and, through test and research on absolute position precision and relative position precision, discovered the fact that the observation parameter determination plays a leading role in navigation-based GPS positioning. It is considered that the setting up of correct observation parameters seems to be an important means for precision improvement of navigation-based GPS single point positioning.
