【摘要】 本文通过推导基线偏差与波长之间的数学关系,在DC算法的基础之上,考虑双频相位双差数学模型本身存在的相等关系,并结合宽巷模糊度组合,提出一种求解整周模糊度的改进直接计算法。在求取模糊度之后,分别采用单历元最小二乘和序贯平差两种解算方案求解基线,以基线长约6.3km、9.1km的两组数据为实例进行求解,并与TGO软件求取的基线向量作比较,试验结果表明了本文方法的正确性和可靠性。更多还原

【Abstract】 The mathematical relationship between the baseline deviation and wavelength was deduced in this paper.Based on Direct Calculation algorithm,a modified direct calculation algorithm was proposed,considering the equal relation existed in double difference model of dual-frequency phase and combining with the wide lane ambiguity.After the integer ambiguity was resolved,the baseline was processed by single epoch least square and sequential adjustment method respectively.Two sets of data with approximate baseline length of 6.3km and 9.1km were solved by the proposed method and the processed baselines were compared with the results by TGO software.The test results showed that the proposed method is accurate and reliable.更多还原
