CONSTITUTION:A pole member 6 is provided, and a GPS antenna 21 is provided in the upper end of the pole member 6, and a transmission antenna 53 is stored in an antenna storage space 63 and is provided under the GPS antenna 21 in the upper part of the pole member 6, and a cable unit 56 is so provided that it connects the antenna storage space 63 and the outside. Thus, the surveyor who moves between survey points only takes the pole member 6 in his hand to hold the transmission antenna 53 and the GPS antenna 21 and only supports the pore member 6 on the survey point to support the transmission antenna 53 in the upper part of the pole member 6. |
