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. RTK GPS provides centimetre level position in seconds, allowing workers to get the precision. 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 the projects, such as highway and bridge, GIS project.
