What is the primary purpose of ISRO’s GSAT-20 (GSAT-N2) satellite?
Show answer & explanation
Correct answer: C
Explanation
Answer: It provides high-speed broadband services across India using the Ka-band.
Explanation:
- GSAT-20, also known as GSAT-N2, is a high-throughput communication satellite developed by 'NewSpace India Limited' (NSIL)—the commercial arm of ISRO. Its primary objective is to provide high-speed broadband services, In-Flight Connectivity (IFC), and maritime communication across the entire country, including India's remote regions as well as the Andaman and Nicobar Islands and Lakshadweep.
- This satellite operates entirely on the Ka-band frequency, which endows it with a significantly higher data transmission capacity compared to earlier satellites. Its total data capacity is approximately 48 Gbps. This satellite is crucial for empowering India's 'Digital India' mission, particularly in regions where delivering internet connectivity via cables or towers is challenging.
Additional Points:
- Launch Details: GSAT-N2 was launched on November 19, 2024, from Florida, USA, using SpaceX's Falcon 9 rocket. This marks the first major commercial collaboration between ISRO and SpaceX.
- Weight and Mission Life: The satellite weighs approximately 4,700 kg; since this exceeded the payload capacity of ISRO's current rockets (which is up to 4,000 kg for the LVM3), it was launched using the Falcon 9. Its mission life is approximately 15 years.
