To provide a position search method which can highly accurately position a facility point, quickly move to the facility point and perform specification in a short time.SOLUTION: A position search method includes a registration step of a desired point 65 and a search step. In the registration step, the desired point is registered in advance with RTK positioning that performs relative positioning between two points. The search of the desired point is performed by a searcher 77 who possesses a mobile station 10 and an instructor 75 who possesses a portable terminal 21 displaying position information of the mobile station. The mobile station and the portable terminal are located on the same point. The method comprises the steps of: making the position information of the mobile station calculated with the RTK positioning the position information of the portable terminal; calculating the position information of the mobile station with the RTK positioning when the searcher who possesses the mobile station moves to the vicinity of the desired point as the portable terminal remains on the same position; and displaying a search instruction image drawing the desired point from the current position of the portable terminal and the position of the mobile station on the portable terminal from the desired point and the position information of the mobile station and the portable terminal.SELECTED DRAWING: Figure 5 【課題】設備地点を高精度で測位し、設備地点への速やかな移動と、短時間で特定が可能な位置探索方法を提供する。【解決手段】所望の地点６５の登録工程と探索工程からなり、登録工程において、２点間の相対測位を行うＲＴＫ測位により所望の地点を予め登録し、所望の地点の探索は、移動局１０を所持する探索者７７と、移動局の位置情報を表示する携帯端末２１を所持する指示者７５とにより行い、移動局と携帯端末とを同一の地点に位置させ、ＲＴＫ測位により算出した移動局の位置情報を携帯端末の位置情報とする工程と、携帯端末の位置はそのままで、所望の地点近傍に移動局を所持する探索者が移動し、移動局の位置情報をＲＴＫ測位により算出する工程と、所望の地点、移動局及び携帯端末の位置情報から、携帯端末に携帯端末の現在位置からの所望の地点及び移動局の位置を描画した探索指示用画像を表示する工程とからなる。【選択図】図５
