Redundant Airport Timing System
Yangon, Myanmar

Yangon International Airport

The Yangon International Airport is the busiest airport in Myanmar. In order to accommodate surging passengers and air traffic, in 2013 the facility underwent a $150 million modernization. The project, completed in 2015, increased the airport’s capacity to 6 million passengers annually. 

Masterclock was chosen as the timing system manufacturer for the airport’s revitalization. The system uses redundant NTP and time code distribution via a 2-channel LTC distribution amplifier and auto-switching power supply for reliable, accurate time synchronization. Terminal work stations, air traffic display boards, and airport security systems all use Masterclock’s precise timing devices to stay in sync. Throughout the facility, 47 of Masterclock's steel-encased NTDS44 digital display clocks provide passengers and employees the correct time utilizing Power over Ethernet (PoE) and Network Time Protocol (NTP).

Estadio De Maracana


The 2014 FIFA World Cup in Brazil brought tremendous opportunity for Brazil to showcase their love and dedication to the sport and massive construction projects were needed to properly prepare the country for the influx of people and attention. Organizers aimed to identify, create, and evolve efficiencies wherever possible to ensure the focus would stay on the games. Handling the millions of visitors pouring through the various facilities was a key element of ensuring that people enjoyed their time and various tactics were utilized to keep these flows as smooth as possible.

Masterclock, working with local distributor Metrum, deployed 78 of our NTDS86 digital displays throughout the facility and utilized the existing network wiring to tie the displays into the rest of the facility network. The displays were configured to remain synchronized to our MCR5000 which was receiving time from the GPS constellation and distributing that accurate time across the network to our displays and various other systems. By ensuring that the facility systems and the staff, visitors, and players were all in sync, Masterclock helped the FIFA World Cup keep the focus on the games and the spirit of the tournament.

Kennedy Space Center

Kennedy Space Center is NASA's rocket launch headquarters, the home of our nation’s outer space and orbiting satellite programs. Users at the Kennedy Space Center (KSC) rely heavily on system synchronization to ensure that various aspects of their operation occur at precise times. Masterclock was tasked with designing a more affordable and efficient method of distributing and displaying these timing signals throughout the facility.

Masterclock designed and built the MDN29 to add additional capabilities to the KSC timing system. The MDN29 accepts the legacy countdown signals (IRIG-B, CS3, CS5) that were previously employed while also accepting distributed countdown and timing information via Ethernet (NTP, IRIG-215-12). These features allow the display to be utilized within current infrastructure while also delivering future possibilities for more efficient integration .

Our contact in the KSC timing group later reported, “These displays will save money by distributing timing and multiple countdowns using spare Ethernet ports and eliminating the need for mechanical switches as well as RS422 distribution. We estimate our total immediate savings on just the lower price alone as $80,870.56".

Schneider ION Meter

Schneider ION Meter

For more than 150 years, Schneider Electric has been known for its excellence and innovative nature in respect to energy management. The company has evolved to master the industry of electricity and automation management. Accurate power metering requires a reliable, consistent timing signature to provide accurate monitoring and reporting. Masterclock was tasked with designing an affordable, accurate solution to compliment the Schneider ION family of meters.

Masterclock re-packaged their time synchronization technology through the creation of the GPS500, which was designed and built to work with the Schneider ION family of meters. The GPS500 was built to receive signals from the 24 GPS satellites in order to calculate an accurate time and distribute it via IRIG-B time code, a PPS (pulse per second) signal or an RS-232/485 (Kinemetrics/Truetime) signal with selectable interval blanking to the ION meter to efficiently track and record electrical consumption.
