GPS has served the principal needs of national timing laboratories for regular comparisons of remote atomic clocks to calculate TAI for the last two decades. Up to now the TAI common-view time links have been organized in three major stations centered at the CRL, the OP and the NIST, which connect about 50 time laboratories around the world. The present way of TAI fixed GPS Common View time links is determined factitiously in order to make the calculation convenient and simple, but the calculated results depend heavily on the quality of observation of the three laboratories (CRL, OP, NIST). In case of one of them does not work properly, TAI calculation will be badly influenced. As far as the technique itself of GPS common-view is concerned, any way of the time links will be feasible. If a slightly more complicated network could be formed with the GPS timing data sent to BIPM by all the time laboratories, the improper result in a closed loop would be largely minimized using the technique of network adjustment. It will supply a more reliable comparison result for TAI calculation. An experimental calculation using the method of network adjustment and its results are presented in this discussion.
