Critical defence communications built by Indian engineers rather than bought abroad — a national capability that stays in the country, and high-skill jobs that come with it. Satellite ground segment hubs are the equipment that lets forces talk and move data over satellite links, and India has historically leaned on foreign systems for parts of this. Avantel, a Hyderabad-based defence electronics firm, has won a ₹117.88 crore contract from DRDO to develop, install and commission a Ground Segment Hub for voice and data communication — designed and built in India.
