Dear chairpersons,

Having learned a bit more about the IGS/BIPM Pilot Project to Study 
Accurate Time and Frequency Comparisons Using GPS Phase and Code 
Measurements during the meeting of the CCTF Working Group on TWSTT 
which took place at our department this week I would like to offer 
our participation. 

Agency:
Technical University Graz
Department of Communications and Wave Propagation
Inffeldgasse 12 
A-8010 Graz

Contact Person:
Dieter Kirchner

E-mail address: 
kirchner@fiwf01.tu-graz.ac.at

Areas of Participation:
Deployment of GPS receivers, H-Maser
Anaysis of instrumental delays
Time transfer comparison
Transportable TWSTFT station

Remarks:
We operate a time laboratory collocated with the GRAZ IGS and 
SLR station. We maintain UTC(TUG) and provide frequency 
and time to the collocated facilities.  We presently operate 3 cesium 
standards (1 5061A and 2 5071A) and use GPS for time transfer 
purposes since 1982 (presently 2  L1, C/A code receivers). We are 
doing TWSTFT since the middle of the 80s. We operate a permanent 
TWSTFT station and a transportable TWSTFT station and participated in 
different experiments in Europe and with the US. Presently we are one 
of the six European and two US stations performing TWSTFT on a 
regular basis.  

Sincerely yours,

D. Kirchner


PS.: On the USNO internet page (GPS Carrier-Phase Time Transfer) one 
 can see an example showing data from the above mentioned stations.
