Calibration of GPS Units for the Pierre Auger Project

The Pierre Auger Project is a high energy astrophysics collaboration that is trying to  determine the mass composition, arrival direction and energy of cosmic ray air showers above 10^19eV.  This is accomplished by using a series of 1600 particle detectors, and an atmospheric fluorescence detector.  Each particle detector will have a Global positioning System (GPS) attached which will be used to precisely  tag the time an event hits a particular detector. This project will concentrate on the calibration of each of the 1600 GPS units with each other and the triggering hardware and software attached to each particle detector.
