| 摘 要： | 严格论证了在对空间或地面目标的定位中,利用伪距测量观测模型的几何因子大于用台站间一次差分观测模型的几何因子.此外,台站间完全差分测量观测的定位精度优于不完全测量情形的定位精度.这些结果给人们在实际工作中采取何种定位方式提供了可靠的理论依据.

| Abstract: | In this paper, we demonstrate that the PDOP obtained via one order difference measuring model among stations is sandier than the PDOP obtained via pseudo distance measuring model and that the accuracy obtained by complete difference measuring is higher than that for partial defference measuring. These conclusion are helpful for our practical works. |
