摘　　要：针对在实际作战中,飞行编队优先考虑战术原则,而忽视JTIDS/MIDS相对导航GDOP的现象。首先利用最小二乘法计算相对导航的GDOP值,其次根据战术原则建立编队模型,最后采用单一变量法,分析了平面位置关系、垂直位置关系及导航源的选择对GDOP值的影响,并将仿真结果与GPS定位导航的GDOP值进行比较。仿真结果证明,位置关系和导航源的选择对于改善相对导航的GDOP值,提高导航精度具有决定性的意义,且仿真结果为实际作战进行编队和选择导航源提供了重要参考。With the phenomenon of tactics taking precedence of GDOP in flight formation of military operations,the paper calculates the GDOP of relative navigation by means of the calculation theory of least square method firstly,then devises a model of flight formation based on tactics and uses the single variable method at last. The author analyzes the effect of horizontal position,vertical position and navigation source on GDOP and compares consequences with GPS’s GDOP. It proves that position and navigation source is decisive for GDOP and accuracy for relative navigation in flight formation and analysis of influencing factors give consultation for how to form into formation and how to choose the navigation source.
