AstroSat is India’s first dedicated multi wavelength space observatory. This scientific satellite mission endeavours for a more detailed understanding of our universe. One of the unique features of AstroSat mission is that it enables simultaneous multi-wavelength observations of various astronomical objects with a single satellite.
The main scientific objectives of AstroSat mission are:
The scientific payload on-board Astrosat are Ultra Violet Imaging Telescope (UVIT), Soft X-ray Telescope (SXT), Large Area X-ray Proportional Counter (LAXPC), Cadmium-Zinc-Telluride Imager (CZTI) and Scanning Sky Monitor (SSM). Know more.
AstroSat Proposal Processing System (APPS) is a web based proposal processing software for the Astrosat mission that facilitates the proposal driven operations and participation of the scientific community. To submit a proposal Click here
This document assists the proposers with the AstroSat proposal preparation and submission using the APPS software, it also acts as the proposers’ manual for the APPS software. Download
The observations will be planned as per mission scheduling. The PI will be informed, after the completion of successful observation for the downloading of processed Level-1 data. Know More
