Next, when the vehicle approaches 3 m around the target point T, the GPS antenna 6 on the mobile station side and the signal processing device 15 (a main part of the positioning device 10) are dropped off from the vehicle. Then, one or two measurers carry the GPS antenna 6 or the like by hand while maintaining the reception state, and approach the vicinity of 30 cm around the target point T while checking the data on the display. When approaching around 30cm around the target point,
A mobile station-side GPS antenna 6 is attached to the dedicated tripod 1 with the automatic leveling device 5 shown in FIG. Then, by turning the arm rail 3 or moving the movable base 4, the position of the GPS antenna 6 is finely adjusted while confirming the data on the display, and the GPS antenna 6 is moved directly above the target point T. When the GPS antenna 6 is moved directly above the target point T, the laser beam 8 is emitted vertically downward from the laser pointer disposed directly below the GPS antenna 6, so that the positioning point 11 is projected on the target point T on the ground surface. Is done. Therefore, the positioning can be completed by driving the wooden pile 9 into the positioning point 11.

As described above, in this apparatus, since the movable base 4 is slidable along the arm rail 3 and the arm rail 3 can be turned horizontally, the final fine adjustment of the GPS antenna 6 to the target point T is performed. Can be easily done. In addition, since the positioning point 11 is projected on the ground by the laser beam 8 vertically emitted from directly below the GPS antenna 6, the positioning can be performed accurately and easily. If the GPS antenna 6 or the like obstructs the operation of hitting the wooden stake 9 at the target point on the ground, the arm rail 3 can be rotated and temporarily evacuated, which does not hinder the operation.

As described above, according to the first aspect of the present invention, the position of the target point is determined by using the GPS, and therefore, compared with the conventional method using a surveying instrument such as a total station. Positioning work can be performed easily and efficiently with a small number of personnel. In particular, since the measurement result by the GPS is directly reflected on the ground surface by the pointer, the rearrangement is unnecessary, and the accurate and accurate positioning can be performed. In addition, in the conventional method, there are many cases where a transmission error of measurement information occurs between an operator of a surveying instrument (a person in charge of distance measurement and angle measurement) and a person in charge of positioning, which may be a major cause of a measurement error. However, according to the apparatus of the present invention, since the GPS information is confirmed and positioned by one measurer, the number of measurement errors is greatly reduced. Therefore, installation of reference points in large-scale civil engineering work such as dam construction and construction work, positioning work in cut-and-fill embankment, positioning work for installation of drainage pipes, etc., pile core for pile driving work When applied to the work of putting out, etc., it exerts an excellent effect. Further, the present invention is not limited to the above-described work, and can be applied to other land-based civil engineering work and construction work, and thus, the efficiency of positioning work in various fields can be expected.
