本发明涉及一种应用卫星定位的无路径导航算法与系统；该系统包括由导航系统获取移动主体的行动能力，以保证获取的导航路径适用于所述移动主体的行动；其次通过卫星信息处理模块基于卫星遥感图像对地面特征的分析，配合设置于移动主体的地面信息获取模块对近距离地面的实时分析，确定多个适合于移动主体的行动区间，从行动区间中进一步通过随机采样一致性算法迭代获得多个优化的线段模型，从而形成多段可连续连接的短途路径，同时计算适合的移动速度，指导移动主体向目标点移动。通过该导航系统实现在无规划导航路径的开放环境下，实现即时的导航演算和规划临时导航路径，并在宏观角度考虑无路径导航条件下的解决方案。 The invention relates to a path-free navigation algorithm and system applying satellite positioning. The system comprises the following steps: acquiring the action capability of a mobile subject by a navigation system so as to ensure that an acquired navigation path is suitable for the action of the mobile subject; secondly, a satellite information processing module analyzes ground features on the basis of satellite remote sensing images and cooperates with a ground information acquisition module arranged on the mobile body to analyze the short-distance ground in real time, and multiple action intervals suitable for the mobile body are determined; a plurality of optimized line segment models are further obtained through iterat
