Which of the following satellites was launched on November 2, 2025, to enhance the Indian Navy’s secure communication network and maritime surveillance capabilities?

The correct answer is

CMS-03 (GSAT-7R)

The question concerns a satellite launched to enhance the Indian Navy's secure communication and maritime surveillance capabilities. The correct answer is CMS-03 (GSAT-7R). Here’s the detailed explanation:

  1. Understanding the Context: The Indian Space Research Organisation (ISRO) frequently launches satellites for various purposes such as communication, earth observation, navigation, and defense. Satellites aimed at defense and communication enhancements are particularly crucial for the Navy and other military services.
  2. Explanation of Options:
    • Cartosat-3: This is an advanced earth observation satellite launched for high-resolution mapping applications. It is not primarily aimed at improving naval communication or maritime surveillance.
    • CMS-03 (GSAT-7R): This is a communication satellite specifically designed for the Indian Navy to enhance secure communication networks and support real-time maritime surveillance. It also replaces the older GSAT-7 (Rukmini) satellite, which served a similar purpose.
    • GSAT-6A: This satellite focuses on multimedia communication and is intended for mobile communication applications. It does not cater directly to the Navy's secure communication and surveillance needs.
    • RISAT-2B: It is a radar imaging satellite designed for reconnaissance and earth observation. While it aids in surveillance, it is not specifically launched to enhance the Navy's secure communication network.
  3. Conclusion: Based on the purpose and functionalities of the satellites mentioned, CMS-03 (GSAT-7R) is the satellite launched on November 2, 2025, to specifically enhance the Indian Navy’s secure communication network and maritime surveillance capabilities.

This answer is justified by matching the functionalities and intended uses of each satellite with the requirements stated in the question.
