    452 In order to avoid the necessity to disseminate the code biases $p^{ij}_3$ and still guarantee that
    453 the client may decently use the code observations we adopted the following approach:
    454 
    455 Denoting the code bias estimated by a server at epoch $t_0$ by $\bar{p}^{ij}_3 = p^{ij}_3(t_0)$ we
    456 modify the satellite clock corrections as follows:
    457 \be
    458 c\bar\delta^{ij} = c\delta^{ij} - \bar{p}^{ij}_3
    459 \ee
    460 and disseminate $c\bar\delta^{ij}$ instead of $c\delta^{ij}$. This modification has no effect on
    461 the processing of phase observations at the client-side (the constant difference is absorb by
    462 estimated ambiguities). For the processing of code observations it has the benefit that the client
    463 does not see the code bias $p^{ij}_3$ but only
    464 \bdm
    465 \bar{p}^{ij}_3-p^{ij}_3
    466 \edm
    467 and we try to keep the difference $\bar{p}^{ij}_3-p^{ij}_3$ lower than a selected threshold.
