仅采用Fr(φ)项的中长基线解算法的研究
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 11
Abstract
仅采用Fr(φ)项的基线向量解算法由于不进行周跳的探测和修复，以及整周模糊度的确定等工作，无法利用双频观测值来消除电离层延迟，因而只能用于短基线向量的解算。利用IGS提供的全球电离层格网图GIM来进行电离层延迟改正，取得了较好的效果，使该算法也能使用于中等长度的基线向量的解算。实际计算结果表明：利用24 h的观测资料和上述方法来计算边长为31 km~107 km的GPS控制网时，基线向量的精度可达0.2 ppm．
