GNSS双频整周关系约束模糊度算法研究

GNSS Dual-Frequency Integer Relationship Constrained Ambiguity Resolution

  • 摘要: 根据GNSS双频载波相位观测值间的特定关系,提出了一种基于双频整周关系约束的模糊度解算方法(FirCAR)。该方法在局部整数范围内可将载波相位的等效波长增长,以利于整周模糊度的快速解算。不同长度的基线数据实验证明了该算法的正确性和有效性,并分析了卫星截止高度角对解算结果的影响。

     

    Abstract: Based on the special relationship of dual-frequency carrier phase observations,GNSS dual-frequency integer relationship constrained ambiguity resolution(FirCAR) is proposed,which enlarges the equivalent wavelength of carrier phase in local integer rang,to achieve a fast integer ambiguity resolution.With the code pseudorange and dual-frequency carrier phase observations,the proposed method resolves integer ambiguities satellite by satellite independently.The correctness and effectiveness of this method have been tested by two baselines of different lengths;and the influence of cut-off angle is also analyzed.
