Cancellation of Face-to-face Workshop on High Precision Timing and Frequency Transfer, 12-13 March 2020
Replaced by: One day Zoom meeting on High Precision Timing and Frequency Transfer, 12 March 2020
We would like to invite you to take part in a videoconference we are planning, led from the Square Kilometre Array Headquarters, Jodrell Bank, UK, focussed on “High precision frequency and timing transfer for next generation radio telescopes using White Rabbit”. The goal is to bring together world experts on precise time and frequency transfer using the White Rabbit system, in order to understand its issues and limitations, and to explore its future use, particularly as it might be applied to the SKA2.
This will be a one day videoconference meeting on Thursday 12th March 2020.

**Given the changes, we would be grateful if you would confirm that you will still be able to give a presentation as listed **
The plan is still to convene a face-to-face workshop once the worldwide health situation has stabilised.
When we are able to hold the in-person workshop we would like to invite demonstrations of the capabilities of the present White Rabbit system. We propose that any hardware should be set up on the first day, and could be left running for the duration of the meeting, with a summary of performance at the end. Anyone wishing to contribute to this part of the meeting is invited to contact Aniket Hendre (a.hendre@skatelescope.org) at the SKAO Headquarters for technical assistance.
We should like to focus on the requirements for SKA2, and will look forward towards the future. Topics we would like to explore include:
- 10Gb/s White Rabbit (and much higher speeds?)
- (Very) long distance WR, including co-existing on existing fibre infrastructure
- Calibration of long haul links (with possible amplifiers etc.)
- Frequency stability as function of distance
- Further improvement potential for frequency stability
This videoconference is being run jointly by the SKAO and the University of Manchester. Please contact the Local Organising Committee if you require any assistance.
