ISRO is set to launch the IRNSS-1H satellite around 7 pm on Thursday from Sriharikota and the 29-hour countdown for the launch began at 2 pm on Wednesday at Sriharikota rocket port. The special thing about this satellite launch is that this is the first time that a satellite is jointly assembled by the space agency and a private firm. Earlier, private firms only used to build components and systems for India’s satellites and rockets. According to the ISRO chairman A.S.Kirankumar, gradually more and more private industry participation will happen in future in the creation of satellites and rockets.
Like its other IRNSS predecessors, IRNSS-1H also carries two types of payloads – navigation payload and ranging payload. Starting July 2013, the Indian space agency has launched seven navigation satellites, with the last one launched on 28 April 2016. Each satellite has a lifespan of 10 years.
