1. A method for using Global Positioning System (GPS) signals to synchronize multiple masters on a stationary network, comprising:
- receiving the GPS signals at the multiple masters on the stationary network;
extracting a time value from the GPS signals at each master;
using the extracted time value to synchronize a local clock at each master; and
using the local clock at each master to synchronize interactions between masters.

Abstract
One embodiment of the present invention provides a system that uses Global Positioning System (GPS) signals to synchronize multiple masters on a stationary network. During operation, the system receives the GPS signals at the multiple masters. Next, the system extracts a time value from the GPS signals at each master, and uses the extracted time value to synchronize a local clock at each master. The system subsequently uses the local clock at each master to synchronize interactions between masters.
