TS19 Best Practice in Positioning

RTK GPS has seen great technological advances over the past few years and is now routinely used in a wide variety of engineering type applications. Around the world, real-time kinematics GPS systems provide with centimeter level position in seconds, allowing workers to get the precision they need at the moment that they need it. The one GPS receiver is placed in a control point (named the reference station) with known coordinates. RTK system combine GPS information and data radio communication with advanced algorithms to calculate precise position of large projects, such as highway and bridge project. But the reference points are most important for surveying and the other applications. The accuracy of the reference points are acquired for survey and stake-out applications. In this article, we tested the most suitable positions for the reference points. And examining the reference points are how influence on the other points in this project
