PERFORMANCE ANALYSIS OF SISPELSAT MSK-DGNSS RADIO SIGNAL IN PENINSULAR MALAYSIA

摘要: Abstract. The use of Global Navigation Satellite System (GNSS) has become essential in providing location based information and navigation. Due to low accuracy navigation solution, differential technique such as radio-beacon DGNSS been used widely augment the user single positioning using GPS. Sistem Pelayaran Satelit (SISPELSAT) is a national system Malaysia consists four broadcasting two monitoring stations operated managed by Marine Department Malaysia. It provides range frequency from 283.5 325 kHz Minimum Shift Keying (MSK) correction service within shore Peninsular In this study, performance SISPELSAT radio signal was assessed on-board Malaysian Vessel (MV) Pedoman MV Pendamar. study area covers 20 km distance extending shoreline with continuous tracking beacon signal. DGPS observation data well coverage strength, signal-to-noise ratio, status were recorded for processing further analysis performance.
