ISRO Satellite Integration and Testing Establishment (ISITE) (Hindi: इसरो उपग्रह एकता एवं परीक्षण संस्थान) is an integrated satellite testing facility established under the aegis of ISRO Satellite Center by Indian Space Research Organisation in 2006. Started with an area of 1000 sq ft. at the time when the Aryabhatta satellite was launched, the testing facility is spread over 100-acre and can integrate and test six satellites of the INSAT class at different stages simultaneously: 2 communications, 2 remote sensing and 2 foreign satellites. The investment on the facility is so far about Rs 220 crore and ISRO plans to make a further investment of Rs 100 crore. The facility has also carried out vibration and acoustic tests of Mars Orbiter Mission (MOM) spacecraft.
The establishment houses four state-of-art facilities:
The facility tests on ground all payload packages for such launch-exposed energy fields for their mechanical effects under simulated conditions. The acoustic tests are designed to induce dynamic responses in the test specimen similar to those experienced in flight to qualify them under flight conditions to ensure trouble-free operation. The acoustic shielding efficiency of heat shields is also tested in this facility. Salient Features of the Acoustic Test Facility:
ISITE has been involved in design and development of more than 50 satellites so far of various types namely:scientific, communication and remote sensing. The center is involved in testing of various types of communications and meteorological satellites which are tested after getting fabricated at Space Applications Centre. The Mars Orbiter Mission was also tested here. Some of the other satellites that have undergone testing at the facility are:GSAT-6, GSAT-7 and GSAT-14.
ISRO has planned to support small and mid-sized industries at its 10-year-old second spacecraft complex, the 100-acre ISITE, at Marathahalli in Bengaluru. The facility is already open to suppliers who assemble and test their spacecraft systems for the ISRO. ISRO is hinging on public-private partnership to increase the frequency of satellite launches.
