Study on the Projection Deformation Problem of GNSS Control Network in High Altitude and Low Latitude Irrigation Areas
Aiming at the problem of projection deformation in GNSS control network in high altitude and low latitude areas,choosing a reasonable projection plane and projection zone to establish a coordinate system,so as to control the projection deformation less than 2.5 cm/km is the key to the problem. This paper theoretically analyzes the influence law of length deformation,puts forward a reason-able solution,and verifies the feasibility of this method in practical engineering through engineering cases.
