Welcome to ISRO Science Data Archive for AstroSat Mission
The science data from observations made by the instruments on board the spacecraft are available for download after the proprietary period from this portal.
ASTROSAT is India’s first dedicated multi wavelength space observatory. This scientific satellite mission endeavours for a more detailed understanding of our universe.AstroSat observes universe in the optical, Ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum. Multi-wavelength observations of ASTROSAT are further extended with co-ordinated observations using other spacecraft and ground based observations.
AstroSat with a lift-off mass of about 1513 kg was launched by India’s Polar Satellite Launch Vechicle (PSLV) on 28th September 2015 into a 650 km circular orbit with an inclination of 6 deg. The spacecraft control centre at Mission Operations Complex (MOX) of ISRO Telemetry, Tracking and Command Network (ISTRAC) at Bangalore carries out the spacecraft health monitoring and control operations. The science data from the spacecraft is downloaded at a dedicated ground station established at Bylalu , Bengaluru and the data is made available to the users through the co-located Indian Space Science Data Centre ( ISSDC). Science data processing, archival and dissemination are carried from ISSDC, the nodal point for the interface with the global scientific and user community.
AstroSat is a proposal -driven, multi –wavelength observatory operated by Indian Space Research Organization (ISRO). ISRO releases periodic calls for proposal submission. Users can submit proposals for operating the science instruments on board using the web based utility AstroSat Proposal Processing System APPS hosted at ISSDC. The science data along with the related software for processing can be downloaded from this portal
