RESEARCH ON ACCURACY TEST OF RTK-GPS DYNAMIC POSITIONING
RTK-GPS动态定位精度测试研究

Background noise of RTK-GPS is tested.Three movement simulation equipments are designed,which are linear movement,sinusoidal movement and circular movement.Positioning accuracy and effects of RTK-GPS under three movement patterns are tested.Test results indicate that the test methods designed can make the positioning accuracy and advantages of RTK-GPS understood directly,which has certain positive significance for extending the application of RTK-GPS in dynamic monitoring of large-scale engineering buildings and natural disasters.
