This project involved a diverse group of people and companies. Besides the seismologists, technicians, and students at SMU, several companies have played major roles. Teledyne-Geotech (now Teledyne-Brown and GSP) supplied the seismometers and preamps for the array. They also built the digitizer used during GSETT-2. Science Horizons developed the communications controller, the element electronics package, and the data center processing software used in the current array.
