Design and development of ocean monitoring system based on GPS

Coastal zone of Malaysia has a vital role in socio-economic and environmental in pursuing the country development. However, it constantly faces a threat from coastal erosion. The report year 2013 from the Department of Irrigation and Drainage Malaysia showed 29% of Malaysian coastal has been experie...

The report year 2013 from the Department of Irrigation and Drainage Malaysia showed 29% of Malaysian coastal has been experiencing erosion at various levels and primarily driven by ocean waves.

The RMS error from data analysis technique is less than 0.0016 m. Validation with Department of Survey and Mapping Malaysia (JUPEM) automatic tide gauges have found both methods agreed on tidal pattern with small discrepancy of less than 10 cm.
