  AstroSat is India's first dedicated multi-wavelength space observatory
launched by the Indian Space Research Organisation (ISRO) on 28 September 2015.
After launch, the AstroSat Science Support Cell (ASSC) was set up as a joint
venture of ISRO and the Inter-University Centre for Astronomy and Astrophysics
(IUCAA) with the primary purpose of facilitating the use of AstroSat, both for
making observing proposals and for utilising archival data. The ASSC organises
meetings, workshops and webinars to train users in these activities, runs a
help desk to address user queries, provides utility tools and disseminates
analysis software through a consolidated web portal. It also maintains the
AstroSat Proposal Processing System (APPS) which is deployed at ISSDC, a
software platform central to the workflow management of AstroSat operations.
This paper illustrates the various aspects of ASSC functionality.
