PROBLEM TO BE SOLVED: To provide a preparation system used for a survey work which installs a stationary station at a reference point in which a position coordinate is unknown and capable of easily specifying the position coordinate of the unknown reference point as a known reference point.SOLUTION: A preparation system used for a survey work according to the present invention is used for the survey work in which a mobile station 2 is placed at an observation point whose position coordinate is unknown, and receives positioning information from artificial satellites Sa1 to Sa4 by the mobile station 2 and a stationary station 1 with the stationary station 1 installed on the reference point whose position coordinate is known, and includes: a calculation step of specifying by calculation a position coordinate of " the unknown reference point A using the positioning information "from the mobile station 2, the positioning information from the stationary station 1, and the position coordinate of the known observation point B" by "placing the stationary station 1 on the unknown reference point A and placing the mobile station 2 at the known observation point B" whose position coordinate is known; and a set step of setting the specified unknown reference point A as the known reference point A by the calculation step. |
