A method for navigation of a movable platform is provided. The method includes the steps. First, a plurality of reflection devices is placed to mark a range. A coordinate location and a direction of the movable platform are received by a positioning system, At least one laser to measure relative positions and distances between the reflection devices and the movable platform are emitted by a laser range finder, respectively. Absolute locations of the reflection devices and the range are calculated by a processor according to the coordinate location and the direction of the movable platform, the relative positions and the distances between the reflection devices and the movable platform. The reflection devices are scanned and tracked by the processor, and the coordinate location and the direction of the movable platform and the absolute locations are calibrated by the processor to control the movable platform to move in the range.
