Abstract

Scanning Sky Monitor (SSM) onboard AstroSat is an Xray sky monitor in the soft X-ray band designed with a large field of view to detect and locate transient X-ray sources and alert the astronomical community about interesting phenomena in the X-ray sky. SSM comprises position sensitive proportional counters with 1D coded mask for imaging. There are three detector units mounted on a platform capable of rotation which helps covering about 50% of the sky in one full rotation. This paper discusses the elaborate details of the instrument and few immediate results from the instrument after launch.

Keywords

Notes

Acknowledgments

SSM team acknowledges Director, ISAC for the constant support for delivery of this payload followed by the successful launch of AstroSat. The team also acknowledges various entities at ISAC who have contributed their part in successful completion of various processes and procedures towards delivery of the payload.
