Spectracom Awarded €600KContract for Synchronization of Digital TV Broadcast Networks

GPS Clocks to Precisely Synchronize Time and Frequency Signals

Paris, June 7, 2012 – Spectracom, a business of the Orolia Group (NYSE Alternext Paris – FR0010501015 – ALORO) and the leading supplier of synchronization for digital broadcast applications, today announced a contract worth nearly 600 k€ from a leading global supplier of broadcast equipment. They will use Spectracom’s GPS Clock synchronization systems for new digital broadcast network infrastructure in Bulgaria.

Synchronization is critical for reliable operation of digital broadcast systems particularly those operating in single frequency mode (SFN). The trend in the industry is to use SFN for digital broadcast since it effectively utilizes the limited availability of radio frequency spectrum. Precisely synchronized time and frequency signals are necessary so digital signals do not interfere with each other to ensure optimum reception by televisions in areas covered by multiple transmitters.

The delivery of Spectracom’s GPS Clocks will be spread throughout the next quarter.


Synchronizing Time Using Presentense

PresenTense offers you an alternative to the limited functionality of synchronizing with Microsoft W32Time program. PresenTense, will not only synchronize all of the Windows PCs on the network, but also provides alert notification and a audit trail which is  not available from the Microsoft W32Time (Windows Time Service). PresenTense Client and Server software is a has Graphical User Interface (GUI) based program that can provide a primary and back-up time reference for redundancy.

Client Software PresenTense Client software synchronizes the PCs to the Time Server and/or another PC on the network that is running the Server software. If the PC can’t reach its Time reference, it can email an alert notification that it can’t be synchronized. PresenTense LAN Time Analyzer is a network time synchronization administrative tool that monitors the time accuracy of all PCs on the network. If a PC exceeds a user-defined accuracy specification, this program can run any exe-based program and can also open a message on the PC’s monitor, alerting to a PC with an error higher than expected and desired

The PresenTense NTP Auditor program provides an audit trail of the PC’s time by comparing the PC’s time to up to three different NTP Time references. This program can provide a continuous print-out for a hard-copy proof that each PC was synchronized at any given moment in time. It also logs this information in a text file sorted automatically by month and day. The time is sampled at set intervals and the error of the PC’s time compared to the reference NTP Time Servers is permanently captured. If the time of the PC is manually set by someone at any time between the scheduled samples, the program automatically triggers an unscheduled sample to permanently log how far off from UTC the PC was manually set and when the event occurred. Once the PC is resynchronized or manually set again, another unscheduled sample occurs again and the time of this occurrence is logged.

Synchronize Multiple Networks from the Same Time Source

With the addition of the 3 port GigE ethernet card you now have the capability to time-synchronize multiple separate networks, from the same unit.  You can read more on the new Netclock 9483 here

Keeping Your Clocks Accurate

Electronic clocks control critical functions in many applications. However, clocks are often designed for low cost rather than for keeping accurate time.

Even fairly accurate computer clocks will vary due to manufacturing defects, changes in temperature, electric and magnetic interference, the age of the quartz crystal, or even system load. Even the smallest errors in keeping time can significantly add up over a long period of time. Consider two clocks that are synchronized at the beginning of the year, but one consistently takes an extra 0.04 milliseconds to increment itself by a second. By the end of a year, the two clocks will differ in time by more than 20 minutes. If a clock is off by just 10 parts per million, it will gain or lose almost a second a day.

Synchronization to GPS

The GPS system synchronizes to 24 satellites each with three or four onboard atomic clocks. The US Naval Observatory monitors the satellites clocks and sends control signals to minimize the differences between their atomic clocks and a master atomic clock for accuracy and traceable to national and international standards (known as UTC).

For time synchronizing a clock, the GPS signal is received and distributed by a master clock, time server, or primary reference source to a device, system, or network so the local clocks are synchronized to UTC. Typical accuracies range from better than 500 nanoseconds to 1 millisecond anywhere on earth.

The GPS clock synchronization eliminates the need for manual clock setting (an error-prone process). The benefits of  GPS synchronization are numerous and include: legally validated time stamps, regulatory compliance, secure networking, and operational efficiency.  At the same time you can synchronize all your devices such as

  • Computer clocks (servers and workstations)
  • Network devices (routers, switches, firewalls)
  • Telecommunications networks (PBXs, MUXs, SONET networks, wireless systems)
  • Critical devices and networks (9-1-1 centers, command and control operations, military test ranges, radar systems, time displays)
  • Physical security systems (video, building access controls, networks)
  • IT security systems (cryptography, authentication, encryption)
  • Facility wall clocks

Where has all the Time Gone

Accurate time of day is important in communications centers and public safety answering points (PSAPs) for time stamping events.  Without accurate time different equipment or systems displays record different times.  There is no correlation or certainty of start/end times for events and tasks and you are left vulnerable to litigation.   The province of Quebec as part of the Civil Protection Act has recently required all 9-1-1 emergency centers ensure that the telephony components and computer systems be synchronized with the official time of the National Research Council of Canada at all times.

Time synchronization with Legal Traceable Time of all your equipment in an emergency call centre (CAD, Radio, VoIP- ANI/ALI, Voice Recorders, etc.) is critical to improve quality of operations, response times and documentation for legal proceedings. This is why the trade organization, National Emergency Number Association (NENA) has determined requirements for synchronized time through the use of master clocks.

The most accurate, secure and reliable method of synchronizing a local installation is through the GPS satellite signals. GPS reception is available everywhere on earth and its time accuracy is traceable to national metrology institutes such as the National Research Council (NRC) and National Institute of Standards and Technology (NIST). Use of a GPS timing signal is the first step to synchronizing the components of your telephony, radio, and computer systems with the official time of the NRC.

When reviewing components for GPS time consider these 5 points

  1. An integral GPS receiver
  2. Network Time Server
  3. Timing outputs for other systems and devices in a communications center
  4. Highly secure web browser interface.
  5. A backup in case of signal loss or the  GPS is disabled or unavailable
