TimePort

Transporting Time

Product Information

TimePort™ is a low power, light weight, portable device that maintains time to within hundreds of nanoseconds of Coordinated Universal Time (UTC) despite being disconnected from both GPS and external power source.

Conventional methods to calibrate time involve transporting a very heavy Caesium atomic clock or running a GPS cable from a convenient outside location into the equipment room and using other test equipment. TimePort™ enables time measurement or calibration at less than 5% of the power, weight and size of transportable atomic clocks and removes the need to provision new or additional GPS cables.

Typical users of this new time service will be financial institutions, telecom networks and power utilities where time delay errors caused by cables, equipment and networks must be quantified and removed to enable services to operate effectively.

Conventional methods to calibrate time involve transporting a very heavy Caesium atomic clock or running a GPS cable all the way from a convenient outside location into the equipment room and using other test equipment to work out the time difference. TimePort™ will demonstrate true innovation by enabling a time calibration service to be undertaken at less than 5% of undertaken the power, weight and size of transportable atomic clock current solutions. Ease of use will be a key attribute enabling operation by non-skilled staff.

Ruth Belville

TimePort™ is a 21^st century equivalent to the 19^th/early 20^th century service of transporting time which was operated by Ruth Belville – “The Greenwich Time Lady” with an 18^th century pocket watch which she calibrated weekly at The Royal Greenwich Observatory.

Whereas the Belville service brought time to London’s Banks in the early 20^th century with accuracies to a few tenths of seconds, TimePort™ will enable time to be transported in the 21^st century using the stability of an atomic clock with nanosecond accuracy.
