Heads-up for NAVISP event on 10/11/2021! Register for the Final Presentation of the Resilient, Trustworthy, Ubiquitous Time Transfer project!
Start date: 10/11/2021 11:00
End date: 10/11/2021 23:59
An accurate, secure and reliable time transfer is a key enabler for emerging fixed and mobile services worldwide. A number of different applications like autonomous vehicles, 5G mobile broadband, mobile multimedia broadcast, power grids, terrestrial positioning services, financial operations, IoT, cloud processing will require secure and reliable time information to be able to work correctly and efficiently. The time information will not only need to be transferred securely, but also accurately and in a seamless and ubiquitous manner, which is quite challenging for solutions based on GNSS only.
It is therefore necessary to put forward innovative and complementary methods of time transfer, focusing on the use of non-GNSS technologies, that would provide secure, ubiquitous, and reliable time information.
To this purpose two network links have been established in Germany between 4 sites (3 GNSS receiver reference stations, 1 at Jülich Forschungszentrum and 2 at GMV offices in Munich and Darmstadt, and 1 client site at PTB, the German national metrology institute in Braunschweig).
One network link is based on an inexpensive Fibre To The Home (FTTH) network access on each site.
The other link is based on a Multiprotocol Label Switching (MPLS) network provision.
Accurate time generated by a time-calibrated multi-frequency GNSS receiver is sent from the server to the client over these two links using two protocols simultaneously: DTM, and NTP. DTM is a proprietary technology with server and client running on Nimbra equipment (developed by Net Insight in Sweden).
In the Final Presentation, the time transfer performance of the different technologies combination (offset and jitter) will be demonstrated.
