Transport

M211

Precision Oscillator

Antenna

GPS Receiver Module

The increase in traffic generally over the past few years has led to considerable congestion of roads, railways, shipping lanes and airspace. Air Traffic Control in particular is of major concern as air transport is increasing at a phenomenal rate and the safety implications are critical. Time & Frequency Solutions have supplied timing and frequency generation equipment for both civil and military ATC applications throughout Europe and Asia and have been instrumental in the development of the Trans-Atlantic ATC network. The GPS8, M210 and M211 instruments are all ideally suited to ATC applications.

Railway signalling systems also require precise time for synchronisation purposes, particularly in high capacity metro and mass transit systems during peak times. Time & Frequency Solutions have supplied a state-of-the-art turnkey synchronisation system for the Hong Kong mass transit system - the busiest system of its type in the world. We have also produced traffic control timing systems for road tolls, tunnels and shipping lanes.

The M210 and M211 modular platforms are particularly suited for Master Clock applications in passenger information applications. A single master clock can drive a large number of both digital and analogue display clocks, together with providing time information to a variety of third party systems. Due to the flexible nature of these products, they are ideally suited to use in multi-vendor environments. The GPS 8 can also be used in this type of application and has been designed with particular regard to the timing and frequency requirements of track to train radio systems.

As with any public service, safety in transport applications is paramount. Time & Frequency Solutions have worked extensively with all of the major vendors of telephone, radio, PAS, PIDS and CCTV systems to ensure interface compatibility, particularly on the M210 and M211 instruments.

The Transport products are complemented by a wide range of Board Level Timing Products and Displays.

Military & Aerospace

M210

M211

Precision time & frequency has long been considered important in Military applications and with recent emphasis on sophisticated secure communications systems this importance has escalated.

As suppliers of systems to the US DoD, the UK MOD and various other defence ministries and contractors world-wide, Time & Frequency Solutions have developed products and systems to support this market. The TFD8000, for instance, was developed primarily to supply the wide range of time, frequency and synchronisation signals required by military platforms, command and control centres and security listening services. Proven in service on board the US Navy's fleet of fast-attack submarines, the TFD8000 has been design and tested to rigorous military standards.

With military budgets under constant scrutiny many new projects are calling for commercial off-the-shelf (COTS) solutions. Time & Frequency Solutions have developed a range of cost-effective products aimed to fill this need whilst retaining the accuracy and reliability expected of Mil-Spec. equipment. The M210 and M211 are option-rich modular platforms providing precise time and frequency interfaces and outputs which are ideally suited for military COTS applications. The M211, for instance, is currently used in NATO radar and communications installations throughout Europe. Together with the GPS8 these products are also suitable for Range Timing, Satellite Ground Stations and Launch Systems.

The Military & Aerospace products are complemented by a wide range of Board Level Timing Products and Displays.

Utilities

RF Receiver

Time & Frequency Solutions have extensively supplied time and frequency standards and instruments for all types of Utility applications including Power Generation and Distribution, Water, Gas and Oil industries together with schools, colleges, municipal offices and even theatres. In many cases, the provision of accurate time is extremely important to ensure that an audit trail is established for safety information, together with precision time measurement for accurate billing of the relevant commodity.

Utility Management systems require time information in a variety of formats and Time & Frequency Solutions have worked with the major suppliers of SCADA and other Control Systems to ensure interface compatibility in this multi-vendor environment. The M210 and M211 products are particularly suited to this type of application due to their modular nature. Accordingly, these products are installed in Oil Rigs, Power Stations, Water Control Centres and other key sites. For electricity applications, there is even an optional module for the M210 and M211 for the precision monitoring of line frequency and line frequency time.

Time & Frequency Solutions have also developed specific instruments for operation in the harsh EMC environment of Electricity Sub-stations. These Sub-station Master Clocks have been extensively proven in this environment, and accordingly, they can be selected with confidence for similar applications.

The Utilities products are complemented by a wide range of Board Level Timing Products and Displays. Included in the Display range are products specifically designed for the electricity industry including a Line Frequency Display and also a Time Error Display, both of which are key indicators in any control room.

Telecoms

TFD8000

Frequency Synthesizer

NTP Interface

Over the past few years increasing demands have been put upon the world's telecommunications networks. The growth in the number of both fixed line and mobile telephone users, the expansion of the internet and the need for increasingly high-speed data transmission have all raised the stakes on the reliability of individual networks and their ability to interface to one another.

One area of considerable concern is network synchronisation and Time & Frequency Solutions have developed products specifically for Primary Reference Clock (PRC) and Stratum 2 and Stratum 3 tracking oscillator applications. The TFD8000 and GPS8 can both be configured to operate as a Primary Reference Clock and the TFD8000 has tracking oscillator module options. The M210 and M211 can both be configured to provide either T1 (1.544MHz) or E1 (2.048MHz) frequency reference outputs for SDH or SONET network synchronisation.

The GPS8 has oscillator and output options designed expressly to meet mobile telephone network base station specifications while the M210 and M211 can both be configured as speaking clocks.

Professional & Scientific

Precision Oscillator

NTP Time Server

Extender Board

LF Simulator

Our extensive range of products covers all areas of the professional and scientific marketplaces from the provision of time in a broadcast studio to the laboratory requirement for ultra precise time and frequency comparisons using the Common View Measurement System. Accordingly, the products offered by Time & Frequency Solutions vary from the simplest analogue clock display to the most sophisticated instrument and within that range, there is a product to fulfil every application.

When logging large streams of scientific data, the ability to tag the data with an accurate time stamp is often a great benefit. However, in certain applications this ability is critical to the performance of the operation. For instance, when logging seismic shocks at various locations during an earthquake the ability to accurately record when a particular shock arrived at each location allows the operator to pinpoint the epicentre of the earthquake to within a few metres. This triangulation technique can similarly be employed for locating thunderstorm activity and vehicle tracking. Time & Frequency Solutions have developed interfaces specifically for this type of application and these are available on the M210, M211 and GPS8 products.

The emergency services are under increasing pressure not just to respond promptly to calls for assistance but to be able to prove that they did so. A timed audit trail allows them to show, legally and unambiguously, the timing of a sequence of events from receiving the emergency call to completion of the operation. Time & Frequency Solutions have worked extensively with all of the major vendors of database systems, voice recorders, voice switches and displays to ensure complete interface compatibility, particularly on the highly flexible M210 and M211 platforms.

Television and radio stations also need accurate sources of both time and frequency for studio and outside broadcast synchronisation, colour sub-carrier generation and as a transmitter reference. The GPS8 is particularly suitable for this type of application.

The Professional & Scientific products are complemented by a wide range of Displays.

Computer Synch.

NTP8

Virtual Instrument Software

PMC-Synclock32

PC/104-SG

ISA-Synclock16

With the rapid increase in the use of computers and networks, a vast array of new applications has appeared for timing, such as the timestamping of financial transactions, safety information and other critical data. Time & Frequency Solutions have developed a comprehensive approach to computer synchronisation in order to meet the wide variety of customer requirements.

Network synchronisation can be achieved on Ethernet networks by means of Network Time Protocol (NTP). Through the use of the NTP8 Timeserver or by fitting an NTP Time Server module into a M210 or M211 Time System, time information is accurately and reliably communicated over the network. For the M210 or M211 Time System, there is also an optional module for synchronisation of an ATM network using Classic IP (CLIP) or LAN Emulation (LANE).

Alternatively, when synchronising a small network of computers, all running Microsoft Windows 95, Windows 98 or Windows NT, all that is needed is a single serial interface from either a GPS8, M210 or M211 to one of the computers in the network, together with the installation of Time & Frequency Solutions' "Synchroniser" software.

A small array of computers can easily be synchronised without using a network by fitting a timing expansion card into each computer. Time & Frequency Solutions supply board level timing cards for ISA, PCI and VME-bus platforms, all of which have timecode inputs and outputs and include optional on-board GPS Receivers.

In its simplest form a single computer can easily be synchronised to international or local time either with a serial interface from a GPS8, M210 or M211 or by fitting an internal timing expansion card with on-board GPS receiver.
