摘　　要：介绍了BDS/GPS组合载波相位双差定位的解算模型,分析了通常模糊度实时算法的不足,根据工程结构变形测量中,监测点初始坐标已知且在一定范围内变化的特点,提出了一种BDS/GPS组合测量系统模糊度单历元实时算法。通过实测的实验数据,验证了本文算法的正确性。And then, In this paper, the double-difference carrier-phase observation model monitoring, according to the characteristic that monitoring points changed an instantaneous ambiguity resolution algorithm for BDS/GPS of BDS/GPS integrated system are discussed. in a small range in engineering deformation integrated system based on prior coordinate constraint is proposed. At last the method is proved with BDS/GPS observables collected in a test project.
