Embodiment Construction
[0057] Such as figure 1 , figure 2 and image 3 As shown, the underground pipeline positioning method based on the CORS system of the present invention includes the following steps:
[0058] Step 1: CORS system establishment: Deploy one or more GPS fixed reference stations 1 in the area to be located where underground pipeline positioning is required. The GPS fixed reference station 1 is a GPS receiving system with a fixed position. The GPS fixed reference station 1 and the data service center 2 carry out two-way communication through the data transmission system, and the data service center 2 and the mobile data processing terminal held by pipeline positioning staff carry out two-way communication through the positioning and navigation data broadcasting system. In communication, the number of the mobile data processing terminal is one or more and it includes a data processor and a parameter input unit and a display unit respectively connected to the data processor; the GPS fixe...
