Abstract

In equatorial region, severe atmospheric delays occur frequently which leads to difficulties in the ambiguity resolution process and thus affects the accuracy of RTK positioning. The idea of N-RTK system which is to reduce distance-dependent errors, enable high accuracy RTK positioning to be achieved over large area. Hence, the N-RTK system has become popular to be implemented by various agencies and universities. A research-based facility of GPS N- RTK positioning system namely ISKANDARnet has been established by UTM-GNSS and Geodynamics Research Group. ISKANDARnet has been set up with adequately inter-stations distance to assist ambiguity resolution. The data quality of each station is essentially checked by analysing multipath vulnerability. Moreover, generation of real-time network corrections and stability of communication link for inter-stations are monitored to ensure the accessibility of the system. Findings of this study are expected to robust research activities and support the development region of ISKANDAR Malaysia.
