Auxiliary telescopes in the neighbourhoods of a main telescope equipped with an LGS can provide, in principle, full sky coverage. The auxiliary telescopes, however, should be able to move around in order to acquire a useful natural guide star (NGS), and to track the LGS, comoving with the scientific target. Detailed expressions and results of numerical simulations are given.
