[3][4] A Data Relay Satellite System (DRSS) facilitates continuous real-time communication between Low Earth orbit bound spacecraft to the ground station as well as inter-satellite communication.
India operates one of world's largest remote sensing satellites systems.
Implementation of the system will be essential for tracking Gaganyaan, India's future crewed spacecraft.
[5] Satellites might carry optical communication payload for increased data security and high transfer rates.
[6][predatory publisher] IDRSS was approved by the Government of India and had funds allocated in budget of 2019-20.
