摘要
根据GPS网平差的基本模型,从理论上分析了GPS基线相关性对GPS网平差结果的影响,推导了相关公式;并通过实例说明在精密GPS控制网平差时,应当考虑基线之间的相关性,以使解算结果达到毫米级精度。
On the basis of basic adjustment model of GPS control network, the effect of GPS correlation between baselines on the adjustment result was analyzed theoretically and the formulea have been derived. The example has demonstrated that the correlation between GPS baselines should taken into account in the adjustment of high precision GPS control network, to reach the accuracy of few millimeter level.
