  In this paper a bisingular pseudodifferential calculus, along the lines of
the one introduced by L. Rodino in [12], is developed in the global setting of
a product of compact Lie groups. The approach follows that introduced by M.
Ruzhansky and V. Turunen [13] (see also V. Fischer [5]), in that it exploits
the harmonic analysis of the groups involved.
