The three private companies—Hyderabad-based Ananth Technologies, and Bengaluru-based Centum Electronics and Alpha Design Technologies—are partners, suppliers and vendors of ISRO, and have played key roles in previous surveillance satellites, as well as landmark Indian space missions such as the successful Chandrayaan-3.

Ananth Technologies, led by former ISRO veteran Subba Rao Pavuluri, was a key supplier of components to the Chandrayaan-3 mission. So, too, was Centum—led by chairman Apparao Mallavarapu.
