Surveying and mapping lofting device based on gnss receiver

The utility model relates to the technical field of surveying and mapping lofting devices, and discloses a surveying and mapping lofting device based on a gnss receiver, which comprises a mounting frame, a moving device is arranged in the mounting frame, a scale is clamped in the moving device, and an auxiliary frame positioned below the mounting frame is arranged on the outer side of the scale. The surveying and mapping lofting device based on the gnss receiver has the advantages of being accurate in adjustment and the like, and solves the problems that an existing total station is provided with a relatively complete positioning system, a scale needs to be continuously adjusted by an operator according to the total station, so that an accurate point is found for lofting, the precision is poor when the scale is manually moved, and the lofting efficiency is high. The problems that in the prior art, due to the fact that the ruler cannot be accurately controlled to move within the needed distance, the ruler is r
