Influence of real-time kinematic network in cadastral surveying

Development of cadastral surveying in Malaysia has showing excellent progress with the application of the latest surveying technology where in the year of 2003 JUPEM has implemented Real-Time Kinematic GNSS Network (MyRTKnet). Currently there are seventy eight (78) GNSS reference stations over the entire country compared with twenty nine (29) a network of Continuously Operating Reference Stations (CORS) in 2003. This study focuses on analyzing the performance of GPS observation using Network based-RTK technique and Virtual Reference Station-RTK technique in conducting cadastral reference mark within a 30 km radius from the existing MyRTKnet Station and also outside a 30 km radius from the existing Reference Station. The test observation carried out on eight Cadastral Reference Mark located at North, Perak. The accuracy of the VRS-RTK in the horizontal component is in the range of 1cm to 2cm. While for the accuracy of N-RTK in horizontal component is in the range 1cm to 2.5cm. Based on the JUPEM circular no. 6/2009 the results acquired are within the tolerance where the coordinate difference between three epochs of observation were less than 3 centimeter for Northing and Easting component
