[time-nuts] Ashtech Z12T

[JF PICARD]

Thank you for answer and sorry for delay. Purpose is simultaneous view of GPS satellites with the french official time laboratory LNE SYRTE . The corrections factors from the laboratory will enable to get with our high performance cesium about 5. 10-13  . Today the cesium is running alone. Discussion with some people involved in this worlwide common practice spoke about the Z12T but if there is anything more modern..

 The Z12T is a bit old by now, although some
 of us own or have used them. Z12 documentation is available
 on multiple archived Ashtech web sites. Lots of conference /
 technical papers describing time transfer with Z12T
 receivers exist. AFAIK a number of national timing labs
 still use them.
 
 What is it you're trying to do? Do you
 own a Z12T and are just looking for spare parts? Or are you
 looking for modern time transfer via GPS / GNSS? If so, what
 level of timing accuracy are you looking for? Perhaps you
 could explain a bit more what your actual request is, or
 what timing infrastructure you already have running.
