India's growth in the field of space exploration has been growing in leaps and bounds, and adding a new feather to the cap will be the launch of India's eighth navigational satellite IRNSS- 1H on Thursday which marks the first time the private sector has been actively involved in assembling and testing of a satellite. While in the past, the private sector has supplied components for satellites, it has not been involved in the actual assembly of a satellite.

The IRNSS- 1H satellite, weighing 1,425kg is to be launched from the second launch pad of the Satish Dhawan Space Centre at Sriharikota, on the ISRO's launch vehicle PSLV-XL.

Chairman of ISRO (Indian Space Research Organisation) A S Kiran Kumar told TOI, "For the first time, a private company has been involved in the integration of a satellite. Progressively, we will involve more and more companies in satellite assembly activities."

"Subsystems of the payload and launch vehicle are already being developed in collaboration with the industry," Kumar added.

Around 25 percent of the development work of IRNSS-1H was successfully completed by a consortium led by Bengaluru-based Alpha Design Tecnologies, under the guidance of ISRO scientists.

Alpha Design CMD HS Shankar revealed that the consortium had already bagged the orders to build IRNSS-1I and work had begun on the project for the satellite which is scheduled for an April 2018 launch.

The need to launch IRNSS-1H came up after 3 atomic clocks on board ISRO's first navigational satellite IRNSS-1A, which had been launched in 2013, had stopped functioning. Imported from European aerospace manufacturer Astrium, the rubidium atomic clocks are used to provide accurate locational data which is used in several earth-based applications, such as navigation and monitoring.

The IRNSS-1H will be launched into a sub geosynchronous transfer orbit after which two solar panels of the satellite will be automatically deployed, and the master control facility at Hassan will perform orbit raising manoeuvres of the satellite.
