SAGARMITRA

Overview

Space Applications Center (SAC), is a major research and development center of the Indian Space Research Organization (ISRO). It plays a key role in realizing vision and mission of ISRO. Located at Ahmedabad, SAC is spread across two campuses having multi-disciplinary activities.

The core competence of the center lies in development of space borne and air borne instruments/payloads and their applications for national development and societal benefits. These applications are in diverse areas and primarily meet the communication, navigation and remote sensing needs of the country. Besides these, the center also contributes significantly in scientific and planetary missions of ISRO like Chandrayan-1, Mars Orbiter Mission etc.

The communication transponders developed at this center for Indian National Satellite (INSAT) and Geo Synchronous Satellite (GSAT) series of satellites are used by government and private sector for VSAT, DTH, internet, broadcasting, telephony etc. These satellites are instrumental in reaching remote parts of the country. The payloads for major navigation systems of the country - Indian Regional Navigation Satellite System (IRNSS) and GPS Aided Geo Augmented Navigation (GAGAN) are being developed by this center.

This center designs and develops the optical and microwave sensors for the satellites, signal and image processing software, GIS software and many applications for Earth Observation (EO) programmed of ISRO. These applications are in diverse areas of Geosciences, Agriculture, Environment and Climate Change, Physical Oceanography, Biological Oceanography, Atmosphere, Cryosphere, Hydrosphere etc.

The facilities at SAC includes highly sophisticated payload integration laboratories, electronic and mechanical fabrication facilities, environmental test facilities, systems reliability/assurance group, image processing and analysis facilities, project management support group and a well-stocked library. SAC has active collaborations with industry, academia, national and international institutes for research and development. The center also has state-of-art in-house and mobile exhibitions to propagate space technology and applications amongst students and public.

Distress Alert Transmitter

Distress Alert Transmitter enables fishermen to send distress messages to Centralized Control Centre in case of any emergency. The network also supports sending acknowledgement of these alerts and other emergency messages to fishermen via the NavIC Messaging Service.
