Since the floating type surveying instrument 1 has the above-mentioned configuration, for example, when surveying on the ground, the floating surveying instrument 1 is installed as follows. That is, in the surveying point SVAR to be surveyed, the surveying point SVAR is divided into triangular unit surveying points USn (n = 1, 2, 3 ...), and the outer circumference of one unit surveying point US1 is shown in FIG. As shown in, the main support column 3, the first and second auxiliary support columns 5 and 6 of the floating device 2, which are set in a form corresponding to a predetermined surveying height H that does not interfere with the surveying station SVAR, are attached to the unit surveying station. It is erected so as to be positioned corresponding to each vertex of the US1 triangle. In consideration of work efficiency of surveying, the main support column 3 moves as much as possible in the next survey (for example, survey of the unit surveying place US2) among the positions corresponding to the respective vertices, as shown in FIG. It is preferable to select a position where it can be eliminated and to set it upright. That is, in the case of this example, the main support column 3 is the unit surveying place US1.
And, it is erected at the position corresponding to the vertex of the triangle common to the unit surveying place US2 to be measured next time. Next, an auxiliary wire 7 is stretched between the first and second auxiliary columns 5 and 6 together with the left / right moving device 30 so that the left / right moving device 30 can move on the auxiliary wire 7. Then, between the stretched auxiliary wire 7 and the winding device 10 provided on the main support column 3, the main wire 13 and the proximity wire 2 are provided via the lateral movement device 30.
1, receding wire 22, leftward wire 23 and rightward wire 2
4 is stretched, and the mounting device 40 is movably suspended and supported on the main wire 13 having a predetermined surveying height H. Since the main wire 13 is wound around the main wire winding section 12 with a predetermined tension, the main wire 13 is stretched without hanging down on the surface of the unit surveying place US1. That is, the mounting device 40 is provided movably over the entire surface of the unit surveying place US1 without contacting the surface of the unit surveying place US1. In addition, the mounting device 40
From the above, the signal cable 53 of the GPS surveying device 50 is stretched to the winding device 10 in the form of being wound by the winding device 10 on the cable winding portion 55 with a predetermined tension in the same manner.
The satellite signal from the artificial satellite received by the GPS antenna 51 mounted on 0 and the antenna height RH detected by the height detection device 60 are signal analysis calculation installed in the vicinity of the main support column 3 via the signal cable 53. It becomes possible to transmit to the machine 52.

After the floating type surveying instrument 1 has been installed on the unit surveying place US1 in this way, the surveyor operates the laser pointer 56 to allow the surveyor to wind the winder 10 close to the main column 3. The mounting device 40 is moved in the approach direction (direction of arrow C) or the retreat direction (direction of arrow D) by operating the portion 15 and the far-back winding portion 16, or the left-hand winding portion 17 of the winding device 10 is moved. And the right-hand winding portion 18 to operate the mounting device 4
0 is moved to the left (direction of arrow A) or to the right (direction of arrow B) so that the reception position RO of the GPS antenna 51 mounted on the mounting device 40 is set to the desired survey point Pn in the unit surveying place US1. (N = 1, 2, 3 ...) Positioning above.
For example, as shown in FIG. 1, when it is desired to measure the position of the survey point P1 in the unit surveying place US1, the laser beam 56a emitted by the laser pointer 56 provided on the GPS antenna 51 mounted on the mounting device 40 is emitted. In order that the designated position LO coincides with the desired survey point P1, the winding units 15, 16, 17, and 18 of the winding device 10 are appropriately operated to move the mounting device 40, and the GPS antenna 51 of the GPS antenna 51 is moved. The reception position RO is positioned on the survey point P1. Then, in the positioned state, the GPS surveying device 50 and the height detecting device 60 are operated to receive the satellite signal emitted by each artificial satellite on the orbit via the GPS antenna 51, and the height detecting device 60 The antenna height RH is detected, and the ground coordinates (X, Y, Z) of the reception position RO of the GPS antenna 51 on the surveying point P1 are detected by the signal analysis calculator 52 based on the received satellite signals and the antenna height RH. And the antenna height RH is subtracted from the calculated ground coordinates (X, Y, Z) to calculate the ground coordinates (X1, Y1, Z1) of the survey point P1 to be surveyed.

Next, when the ground coordinates (X1, Y1, Z1) of the surveying point P1 are acquired by the GPS surveying device 50 in this manner, the winding device 10 is appropriately operated to set the GPS at the new surveying point P2 or the like. By repeating the measurement by moving the antenna 51, it is possible to measure the necessary measurement points in the unit surveying place US1. In addition, the surveying operator is the winding device 1
Only by appropriately operating 0, the mounting device 40 can be moved and driven to an arbitrary position in the unit surveying place US1 in the vicinity of the main column 3, so that the surveying work can be efficiently performed by one person. Next, when the surveying within the unit surveying place US1 is completed, for example, as shown in FIG. 1, the surveying within the unit surveying place US2 indicated by the alternate long and short dash line in FIG. 1 adjacent to the unit surveying place US1 is started. That is, as described above, the first and second auxiliary columns 5 and 6 are provided on the outer circumference of the unit surveying place US2 in such a manner that the auxiliary wires 7 are stretched to correspond to the vertices of the triangle of the unit surveying place US2. It is erected so as to be located so as to be moved from the outer circumference of the unit surveying place US1. As shown in FIG. 1, the main support column 3 does not need to be relocated because it is erected at a position corresponding to the apex of the triangle common to the unit surveying locations US1 and US2. Then, the mounting device 40 is provided movably over the entire surface of the unit surveying place US2 without contacting the surface of the unit surveying place US2. Therefore, as described above, the desired survey point Pn (n = 1, 2, 3, ... In the unit survey location US2).
...) on the GPS antenna 5 provided on the mounting device 40.
Move 1 and take a survey. Then, after the survey at the unit surveying place US2 is completed, the surveying at the surveying place SVAR is completed by repeating the surveying inside the unit surveying place USn (not shown) adjacent to the unit surveying place US2.

As described above, the surveyed area SVAR to be surveyed
The GPS antenna 51 is attached by moving the mounting device 40 equipped with the GPS antenna 51 on the auxiliary wire 7 and the main wire 13 provided at a predetermined surveying height H that does not cause an obstacle in the surveying area SVAR. Without installing a tripod, etc. on the surface of the surveying site SVAR,
That is, the GPS antenna 51 can be installed at an arbitrary position in the surveying place SVAR without contacting the surface of the surveying place SVAR. , A place where there is a restriction such as standing a tripod or a rough surface caused by a surveyor entering, and also in the middle of a road, in a field, in a river or pond, or on soft ground. As described above, even in a place where it is difficult for a tripod or the like to be erected or a surveyor to enter, it is possible to easily perform surveying by the GPS surveying device 50. Therefore, regardless of the form of the surveyed area, restrictions, etc., the survey can be easily performed using GPS. Further, since the GPS antenna 51 is mounted on the mounting device 40 via the pivot portion 43, the GPS antenna 51 is always maintained in the horizontal state regardless of the movement of the mounting device 40, so that the satellite signal emitted by the GPS satellite is transmitted. It is possible to always receive in good condition, and it is possible to measure accurately. Further, since the laser pointer 56 is mounted on the mounting device 40 via the pivot portion 43, the pointing position L designated by the laser pointer 56 on the surveying location SVAR is irrespective of the movement of the mounting device 40.
Since the relative position between O and the reception position RO of the GPS antenna 51 is constant, the indicated position LO and the reception position RO are fixed.
The relative position with respect to is easy to correct, and the survey can be easily performed. Furthermore, by subtracting the antenna height RH obtained by the height detection device 60 from the height component of the ground coordinates (X, Y, Z) of the reception position RO of the GPS antenna 51 obtained by the GPS survey device 50, the survey point is obtained. Since it is possible to obtain not only the planar position of Pn but also the position in the height direction, it is possible to measure the three-dimensional position of the survey point Pn.

It should be noted that in the above-mentioned embodiment, the surveying point S
VAR is a triangular unit survey location USn (n = 1, 2, 3
..), so that as the floating device 2, three columns of the main column 3, the first and second auxiliary columns 5, 6 were erected, but if at least two columns are erected, A guide wire such as the auxiliary wire 7 and the main wire 13 can be stretched between the struts, and the mounting device 40 can be moved and driven on the wires without contacting the ground surface. It goes without saying that the moving range of the mounting device 40 may be appropriately set by arranging two columns, four columns or the like upright depending on the purpose of surveying or the like. Further, although the mounting device 40 is supported and guided by the linear members such as the wires 7 and 13 in the above-described embodiment, it goes without saying that a member having rigidity may be used. Further, in the above-described embodiment, the mounting device 40 is connected to the proximity wire 21 and the receding wire 2 of the winding device 10.
2. The mounting device 40 is moved and driven in an arbitrary direction by winding and winding the wires such as the leftward wire 23 and the rightward wire 24. However, even if the mounting device 40 is provided with a movement driving device, it can be self-propelled. Needless to say good things.
