The Sumatran GPS Array is being designed, constructed and operated by members of the Tectonics Observatory at Caltech and the Indonesian Institute of Sciences (LIPI). The SuGAr data are processed and archived at SOPAC (Scripps Orbit and Permanent Array Center). Funding for the SuGAr comes to the Tectonics Observatory solely from the Gordon and Betty Moore Foundation.

The Observatory is pleased to make the SuGAr data available to anyone who wishes to use them. However, if you use these data in your published work, the TO requests that you acknowledge the scientists and technicians of the Tectonics Observatory, LIPI and SOPAC, who are establishing, maintaining and operating the array.
