Suitability analysis for DGPS radio beacon establishment at Port Klang Malaysia

Differential Global Positioning System (DGPS) is a positioning technique which provide safety in navigation to support maritime activities. Marine Department of Malaysia has established Sistem Pelayaran Satelit (SISPELSAT) as safety to aid maritime navigation activities system over the coast of Peninsular Malaysia. The aim of this study is to investigate the location suitability for a new SISPELSAT radio beacon station at Port Klang, Selangor. The work involves three (3) parts; (1) multipath analysis, (2) GPS and Medium Frequency (MF) signal interference investigation, and (3) DGPS correction transmission signal simulation coverage. It has found that, the location has an acceptable multipath value of MP1 and MP2 at 0.4097m and 0.3654m respectively. Meanwhile, no signal interferences on GPS and MF radio signals have found at the proposed location. In addition, the signal simulation shows that the location of Port Klang station are able to provide optimum DGPS coverage for the area of Melaka Straits.
