为解决不同GNSS间信号差异引起的多GNSS RTK/INS紧组合导航应用中卫星系统间模糊度固定失败的问题, 本文提出顾及ISB/IFB的多GNSS RTK/INS紧组合导航方法, 以进一步发挥多GNSS在复杂环境下的互补性和灵活性。本文推导了顾及ISB/IFB的多GNSS RTK/INS紧组合导航观测方程, 给出了综合利用抗差估计方法和粒子群优化的ISB/IFB参数估计方法。试验结果表明, 顾及ISB/IFB参数可以在一定程度上提高卫星系统间模糊度固定成功率; 结合抗差估计方法提高卡尔曼状态估计浮点解精度, 可显著提高多GNSS RTK/INS紧组合导航系统在复杂环境下的系统间模糊度固定成功率与导航精度。
