Comparison of MyRTKnet Performance with Various Real-Time Corrections Based on Different Time

Abstract Virtual Reference Station (VRS), Master-Auxiliary Corrections (MAX), Individualised (IMAX), Nearest Base, and Network D-GNSS are among the Real-Time Kinematic (NRTK) techniques supported by Malaysia GNSS (MyRTKnet) in providing network-based solutions to users. However, different network corrections have limits due characters, thus offering a variety of position accuracy. Therefore, this study evaluated accuracy real-time corrections, VRS, MAX, IMAX, D-GNSS, for coordinates at two times, morning evening. The was conducted times make it easier users choose suitable quality time conduct observations. This research implemented on pillars calibration site Politeknik Sultan Haji Ahmad Shah (POLISAS) Kuantan, Pahang. pillar become benchmark differentiate with correction coordinates. result that difference can be used analyse level corrections. study’s findings show VRS type is most stable has highest Base MAX also give relatively good improved increasing observation depending area. IMAX produces inconsistent results low accuracy, but some applied obtain as utilises code measurement only. concludes best VRS. produce acceptable safely chosen over D-GNSS.
