Abstract

A preparation system for surveying operation of the present invention includes a mobile station disposed at a known observation point and a fixed station disposed at an unknown reference point. The preparation system includes an arithmetic step to determine the position coordinate of the unknown reference point based on positioning data received by the mobile station, positioning data received by the fixed station, and a position coordinate of the known observation point, and an assigning step to assign the unknown reference point whose position coordinate is determined as the known reference point.

1. A preparation system for surveying operation, comprising:

a mobile station disposed at an observation point where a position coordinate is known; and

a fixed station disposed at a reference point where a position coordinate is unknown,

wherein the system comprises;

an arithmetic step to determine the position coordinate of the unknown reference point based on positioning data received by the mobile station from satellites, positioning data received by the fixed station from the satellites, and a position coordinate of the known observation point, and

an assigning step to assign the unknown reference point whose position coordinate is determined as a known reference point.

2. The system according to claim 1, wherein

the mobile station includes at least a mobile-station satellite positioning section that receives the positioning data from the satellites, and

the fixed station includes at least:

a fixed-station satellite positioning section that receives the positioning data from the satellites, and

an arithmetic section that sets the positioning data received by the fixed-station satellite positioning section as an initial positioning data, determines a horizontal relative position relationship between the unknown reference point and the known observation point based on the initial positioning data and the positioning data received by the mobile-station satellite positioning section, determines a horizontal position coordinate of the unknown reference point based on the determined horizontal relative position relationship and a horizontal position coordinate of the known observation point, and assigns the determined horizontal position coordinate as a horizontal position coordinate of the known reference point.

the mobile station includes a target to measure a height, and

the fixed station executes:

an arithmetic step to determine the horizontal relative position relationship between the unknown reference point and the known observation point,

a determination step to determine a vertical position coordinate of the unknown reference point by measuring the height of the target and acquiring a relative height of the fixed station with respect to the target, and

an assigning step to assign the determined vertical position coordinate as a vertical position coordinate of the known reference point.

4. The system according to claim 2, wherein

the mobile station includes a target to measure a height, and

the fixed station executes:

an arithmetic step to determine the horizontal relative position relationship between the unknown reference point and the known observation point,

a detection step to detect an altitude angle of the target with respect to a reference surface, and

a determination step to determine a vertical position coordinate of the fixed station based on the determined horizontal relative position relationship and the measured altitude angle.
