  Galaxies, as well as their satellites, are known to form within the cosmic
web: the large, multi-scale distribution of matter in the universe. It is known
that the surrounding large scale structure (LSS) can impact and influence the
formation of galaxies, e.g. the spin and shape of haloes or galaxies are
correlated with the LSS and the correlation depends on halo mass or galaxy
morphology. In this work, we use group and filament catalogues constructed from
the SDSS DR12 to investigate the correlation between satellite systems and the
large scale filaments they are located in. We find that the distribution of
satellites is significantly correlated with filaments, namely the major axis of
the satellite systems are preferentially aligned with the spine of the closest
filament. Stronger alignment signals are found for the cases where the system
away from the filament spine, while systems close to the filament spine show
significantly weaker alignment. Our results suggest that satellites are
accreted along filaments, which agrees with previous works. The case of which
away from the filament spine may help us to understand how the filament forms
as well as the peculiar satellite distribution in the Local Universe.
