GPS Modules

GPS Modules are easy-to-use, microprocessor-based Universal Time Base (UTB) devices that provide accurate time-of-day information for traffic signal controllers. The module retrieves time signals from the atomic clocks of the United States National Institute of Standards broadcast on the GPS satellite network. The modules then decode the signals and interfaces with the traffic control equipment.


  • Synchronize time-of-day to GPS
  • Update daylight savings and leap second time corrections automatically
  • Comply with Caltrans requirements for global positioning latitude and longitude
