The Indian Space Research Organisation will launch 83 satellites at one go in January 2017, a first-of-its-kind mission for the agency. Of these, three are indigenous, while the remaining 500-kg vessels were manufactured in the United States, Israel, Switzerland, Netherlands and Kazakhstan, PTI reported.

“These international customer satellites are being launched as part of the commercial arrangement between them and Antrix Corporation Ltd, the commercial arm and PSU under the ISRO,” Minister of State for the Prime Minister’s Office Jitendra Singh told the Lok Sabha on Wednesday. The Department of Space falls under the PMO.

The three Indian 730-kg, Cartosat-2 series satellites that will be launched as primary payload include the INS-IA and INS-1B.
