摘 要:在南极开展GNSS大地控制网建设,布设大地测量控制点标志,是开展测绘工作的基础,是丰富我国测绘地理信息成果的重要依据。受南极恶劣自然环境和南极科考工作时间短暂等不利因素的影响,以往布设在南极的GNSS大地测量控制点标志存在着风化、松动、移位等现象,严重影响了测量定位精度。2019年,针对以往布测大地控制点出现的问题,提出新的设计构思,并付诸实施。The construction of GNSS geodetic control network in Antarctica and the layout of geodetic control points are the foundation of surveying and mapping work,the important basis for enriching the results of surveying and mapping geographic information in China and reflecting the sense of existence in Antarctica.Due to the adverse factors such as the harsh natural environment in Antarctica and the short time of scientific research in Antarctica,the GNSS geodetic control points that were set in Antarctica in the past have the phenomena of weathering,loosening and displacement,which seriously affect the accuracy of measurement and positioning.In 2019,in view of the problems of previous geodetic control points,a new design concept is proposed and put into practice.
