      AstroSat is India’s first dedicated astronomical observatory in space with multi-wavelength payload on a single platform. It enables simultaneous observations in the desired wavebands. The increase in the number of payloads has also led to an increase in the complexity in space segment design, groundsegment design, and mission operation management. Each payload instrument and mainframe has its own constraint for the operation, which needs to be satisfied to ensure the safety of the systems. In this paper, we explain the challenges in ground operations for mission management with various constraints. Also, we list the various constraints, both geometric and otherwise, with respect to the mainframe systems and payload instruments of AstroSat.

      AstroSat, India’s first observatory class satellite, operates as a proposal based observatory. AstroSat carries five science payloads capable of simultaneous observations in a broad energy band. In this article, we will summarize the science operations of AstroSat, AstroSat user distribution, user support available for AstroSat users and publications related to AstroSat and AstroSat data.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
