This paper aims at realization of a new method for acquiring high-precise three-dimensional coordinate of a pipeline in a excavation groove which has not been practiced until now by a GNSS surveying device. The prototype development of the surveying equipment was carried out, and it was confirmed that the measurement error of this surveying method was the level which can be practically used by the surveying of multiple workers.
