The aim of the project is to estimate present-day glacial isostatic adjustment in East Antarctica.

Remote, solar-powered GPS installations have been made at sites in the Prince Charles Mountains and Enderby Land. Sites are equipped with power-controlling devices that hibernate the systems when there is insufficient power to maintain operations, then awaken the systems after winter upon the return of the sun. Satellite phone communications permit the automated transmission of data from the sites back to Canberra.
To estimate present-day glacial isostatic adjustment in East Antarctica, thereby providing constraints on GIA models.
The sites were the first installations of permanent GPS equipment in the region. New power-controlling technology was developed for this project and worked successfully, with up to 220 days/year being observed on solar-power alone.
