A "Second Generation" GPS-Based Volcano
Deformation Monitoring System

 

This project is concerned with the development and deployment of a second generation Permanent Automatic GPS Array System on an active volcano, Mt. Papandayan, in Indonesia. This GPS deformation monitoring system was to be a significant advance on earlier designs. A two-stage network design was used: an inner network consisting of relatively low-cost GPS receivers surrounded by a few dual-frequency GPS receivers. The combined network would cost one fifth to one tenth a conventional system, and through the application of special data processing strategies and algorithms should be able to deliver centimetre level accuracies, during long periods of continuous operation.

The low-cost, single-frequency GPS network established in July 1999 was upgraded with the deployment of three dual-frequency GPS base station receivers. First field testing of this hybrid system was carried out in early 2000. This project was undertaken by the then PhD student Volker Janssen.
