Science & Technology MCQs

The indigenous rubidium atomic clock in NVS satellites ensures high precision in timekeeping, which is critical for accurate positioning and navigation.

ISRO uses the GSLV (Geosynchronous Satellite Launch Vehicle) to place the heavy NVS navigation satellites into their intended orbit.

The NVS series of satellites are the next-generation satellites for the NavIC (Navigation with Indian Constellation) system, replacing the older IRNSS satellites.

India's DSN expansion primarily involves enhancing the capabilities of its existing facilities, notably by upgrading and adding larger antenna dishes (like the 32-meter antenna) to improve signal reception and transmission for more distant and complex missions.

The Indian Deep Space Network (IDSN) is located at Byalalu, approximately 40 km from Bengaluru, Karnataka, and is operated by ISRO.

A Deep Space Network is essential for sending commands to and receiving telemetry data from spacecraft engaged in missions beyond Earth's orbit, such as lunar, Martian, or other planetary probes.

The next-gen communication satellites are designed to support a wide range of services including DTH, high-speed broadband, and mobile communication, addressing the increasing digital needs of the country.

Electric propulsion systems offer higher fuel efficiency, allowing satellites to carry less propellant and thus extending their operational life in orbit, which is a key feature for next-gen communication satellites.

ISRO's Next-Gen Communication Satellite Project aims to develop satellites with enhanced data throughput, longer operational life, and greater indigenous content to meet future communication demands.

Quantum computing holds immense potential for applications in drug discovery, material science, financial modeling, and cryptography, which are key research areas in India.
