Space Application Center (SAC), Ahmedabad

Space Applications Centre (SAC) at Ahmedabad is spread across two campuses having multi-disciplinary activities. The core competence of the Centre 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 Centre also contributed significantly in scientific and planetary missions of ISRO like Chandrayaan-1, Mars Orbiter Mission, etc. The communication transponders developed at this Centre 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, telephones etc.

Main Engine and Stage test Facility at IPRC This centre also designs and develops the optical and microware sensors for the satellites, signal and image processing Software, GIS software and many applications for Earth Observation (EO) programme 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 include 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.

Since then, SAC has developed and built a number of satellites for the IRS program, including the IRS-1B, IRS-1C, IRS-1D, Cartosat-1, Cartosat-2, Cartosat-3, Resourcesat-1, Resourcesat-2, Megha-Tropiques, SCATSAT-1, OCEANSAT-2, GSAT-1, GSAT-2, GSAT-3, GSAT-4, GSAT-5, GSAT-6, GSAT-7, GSAT-8, GSAT-9, GSAT-10, GSAT-11, GSAT-12, GSAT-13, GSAT-14, GSAT-15, GSAT-16, GSAT-17, GSAT-18, GSAT-19, GSAT-20, GSAT-21, GSAT-22, GSAT-23, GSAT-24, GSAT-25, GSAT-26, GSAT-27, GSAT-28, GSAT-29, GSAT-30, GSAT-31, GSAT-32, GSAT-33, GSAT-34, GSAT-35, GSAT-36, GSAT-37, GSAT-38, GSAT-39, GSAT-40, GSAT-41, GSAT-42, GSAT-43, GSAT-44, GSAT-45, GSAT-46, GSAT-47, GSAT-48, GSAT-49, GSAT-50, GSAT-51, GSAT-52, GSAT-53, GSAT-54, GSAT-55, GSAT-56, GSAT-57, GSAT-58, GSAT-59, GSAT-60, GSAT-61, GSAT-62, GSAT-63, GSAT-64, GSAT-65, GSAT-66, GSAT-67, GSAT-68, GSAT-69, GSAT-70, GSAT-71, GSAT-72, GSAT-73, GSAT-74, GSAT-75, GSAT-76, GSAT-77, GSAT-78, GSAT-79, GSAT-80, GSAT-81, GSAT-82, GSAT-83, GSAT-84, GSAT-85, GSAT-86, GSAT-87, GSAT-88, GSAT-89, GSAT-90, GSAT-91, GSAT-92, GSAT-93, GSAT-94, GSAT-95, GSAT-96, GSAT-97, GSAT-98, GSAT-99, and GSAT-100.

SAC has also developed and built a number of satellites for other applications, including the INSAT (Indian National Satellite) program, the GSAT (Geostationary Satellite) program, and the EDUSAT (Educational Satellite) program.

SAC has achieved a number of successes in its mission to develop and build satellites. Some of these successes include:

The launch of the IRS-1A satellite in 1988, which was the first Indian satellite to be launched into a polar orbit.
The launch of the Cartosat-1 satellite in 1999, which was the first Indian satellite to be launched into a sun-synchronous orbit.
The launch of the GSAT-1 satellite in 2001, which was the first Indian satellite to be launched into a geostationary orbit.
The launch of the EDUSAT satellite in 2004, which was the first Indian satellite to be launched for educational purposes.

SAC is currently working on a number of new projects, including the development of the Aditya-L1 mission, the Gaganyaan mission, and the Chandrayaan-

(A) True
(B) False
The Big Bang theory is the prevailing cosmological model for the universe. It states that the universe was once in an extremely hot and dense state that expanded rapidly. The Big Bang theory is supported by a variety of evidence, including the cosmic microwave background radiation and the abundance of light Elements in the universe.
(A) True
(B) False
The universe is expanding at an accelerating rate. This means that the distance between galaxies is increasing over time. The expansion of the universe is thought to be caused by dark energy, a mysterious force that makes up about 70% of the universe.

(B) False
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. Black holes are thought to form when massive stars collapse at the end of their lives. Black holes are very difficult to study because they are invisible. However, astronomers can study black holes by observing the effects they have on the objects around them.
