Abstract
A survey system is provided having GPS receivers and using a global positioning system. A reference station main body is provided for surveying; and a plurality of GPS survey apparatuses are provided. They include at least a reference station and a measuring station. The reference station main body has a coordinate composite conversion unit which composes a composite coordinate value of a single coordinate system from GPS data input via an input portion and reference station data measured at the reference station main body. An output device outputs the coordinate value composed by the coordinate composite conversion unit.
