- *... the possibility to construct a time link between
|
|
|
|
radio-observatories at Metsähovi and Onsala was
|
|
|
|
investigated. In Finland the only viable way of
|
|
|
|
accomplishing this goal is by using the Precision Timing
|
|
|
|
Protocol White Rabbit, PTP-WR, to link MIKES and Metsähovi.*
|
|
|
|
- *These first steps towards the implementation of the White
|
|
|
|
Rabbit protocol demonstrate the capability to extend the
|
|
|
|
range of WR towards 1 000 km distance.*

- *The aim of the project NEAT-FT is to investigate new
|
|
|
|
techniques for phase-coherent comparison of remotely located
|
|
|
|
optical clocks, separated by distances of up to 1500 km
|
|
|
|
using optical fibre links. Within the scope of the JRP the
|
|
|
|
equipment necessary for reliable operation of fibre links
|
|
|
|
will be developed and all technological steps towards a full
|
|
|
|
optical link infrastructure demonstrated. Beside frequency
|
|
|
|
dissemination, new techniques for time transfer over optical
|
|
|
|
fibre networks will be investigated in order to provide
|
|
|
|
better timing signals than currently available with GPS
|
|
|
|
receivers. For typical spans of up to 100 km the JRP aims to
|
|
|
|
improve the accuracy down to about 100 ps. Furthermore, the
|
|
|
|
feasibility of a European fibre network connecting optical
|
|
|
|
clocks in Europe will be studied in close collaboration with
|
|
|
|
potential fibre providers.*
