The invention belongs to the field of aircraft route design, and relates to a navigation method and device for adaptively adjusting the global time. The method comprises the following steps: S1, calculating a modified appointed moment of a task waypoint according to a task demand; S2, according to the current position and the flight speed of the aircraft, calculating the predicted arrival time tothe mission waypoint; S3, judging the validity of the modified agreed moment, and if the modified agreed moment is valid, calculating the time difference between the predicted arrival moment and the modified agreed moment; and S4, accumulating the time difference to each waypoint behind the task waypoint in a flight plan. According to the invention, global time self-adaptive modification can be automatically carried out on the flight plan, so that the aircraft can successfully complete the flight mission.

    本申请属于飞机航线设计领域,涉及一种自适应调整全局时间的导航方法及装置。该方法包括:步骤S1、根据任务需求计算任务航路点的修改后约定时刻;步骤S2、根据飞机当前位置和飞行速度,计算至所述任务航路点的预计到达时刻;步骤S3、判断所述修改后约定时刻的有效性,若修改后的约定时刻有效,则计算所述预计到达时刻与所述修改后约定时刻间的时间差;步骤S4、将所述时间差累积到飞行计划中,所述任务航路点之后的每一个航路点上。本申请能够自动的对飞行计划进行全局时间的自适应修改,使飞机能够圆满完成飞行任务。
