Nowadays, Global Navigation Satellite Systems (GNSS) methods are broadly utilized to determine positions of points. This study was conducted with the aim of determining the positioning of control points at Politeknik Kuching Sarawak Campus using GNSS-RTK Technique. For this purpose, twenty-four control points were established with an average baseline length between Base station and Rover less than 1 km were occupied with Topcon HiPer VR receivers for different time periods. In this study there are situation of positioning under satellite obstruction such as the control points situated in the near buildings. Multipath is a common challenge in GNSS-RTK especially in complex environments. The final result from the Horizontal and Height differences were determined and compared with those measured by both static and RTK surveys. The result of the study shows that GNSS-RTK positioning method ensure high accuracy GNSS position solution within few centimetres.
