The Precise Time and Time Interval (PTTI) conference will take place November 16-19 in New Mexico, USA.

GMV and INRiM (the Italian metrological institute) will be presenting a joint paper about how to synchronize a network of master clocks located worldwide and connected to GPS receivers, using the ODTS algorithm in magicGNSS. The PTTI ’09 program is here (see Paper 50, Thursday, Nov 19).

To support the paper and presentation, INRiM and GMV, with the collaboration of other timing labs in Europe and America, have set up an experiment to synchronize eight master clocks via GPS in near-real time. The GPS station names are: brus, ieng, ptbb, roap, sp01, sp02, spt0, and usn3.

The station data (hourly RINEX files) is uploaded every hour onto a dedicated magicGNSS account, and processed in ODTS automatically using the Scheduler. The reference station in ODTS is brus. ODTS processes data in batches of 2 days.
