PMoS - a Real Time Precise DGPS Continuous Deformation Monitoring System

Adam Lowry and Roderick MacLeod

Abstract:	In response to eruptions in 1994 of the volcanoes around Rabual, on the island of New Britain, the Papua New Guinea Government asked the Australian Geological Survey Organisation to look for a more effective method of monitoring the ground movement to assist in predicting further volcanic activity. While GPS had the potential to carry out this task, the difficulties associated with the limited infrastructure of the area, coupled with the requirement to provide accurate positions for multiple sites in real time, back at a central point made it a unique problem. The resultant system developed by SAGEM Australasia Pty Ltd uses an integrated GPS and telemetry design, to provide real time position monitoring to an estimated accuracy of 5 mm + 1 ppm, for multiple remote sites from one base monitoring site. The system has been designed to be portable, easy to set up and operate, and can be applied to any precise monitoring function such as mining, engineering and scientific applications. Moreover the system is not limited to fixed remote operations and can used in dynamic applications with a minimal degradation in accuracy.
