India, which has set its eyes to be a serious player in the multi-billion dollar satellite industry, has roped in the private sector to manufacture satellites. After conducting 150 missions over three decades, the country's nodal space agency ISRO has tasked a consortium to make two big satellites for India's navigation system. Alpha Design Technologies, which will lead the consortium, is a Rs. 400-crore defence equipment supplier. But ISRO is expected to take the firm though the complex process of development - which can take at least six months. Already, a team of 70 engineers is working hard to make a flight ready satellite.
