Understanding the NVS-02 Satellite's Purpose

The question asks us to identify which Indian system the NVS-02 satellite, expected to launch in 2025, is designed to enhance or supplement. This involves understanding India's satellite-based systems, particularly those related to navigation.

Key Indian Satellite Systems Explained

Let's look at the provided options to understand their functions:

• NavIC (Navigation with Indian Constellation): This is India's own regional satellite navigation system. It provides accurate positioning information services similar to GPS but is specific to India and its surrounding regions.
• INSAT (Indian National Satellite System): This is a series of multipurpose geostationary satellites managed by ISRO. INSAT satellites are used for various applications like telecommunications, broadcasting, meteorology, and disaster management support, but not primarily for navigation.
• IRNSS (Indian Regional Navigation Satellite System): This was the original name for India's regional navigation satellite system before it was officially renamed NavIC.
• GSAT (Geosynchronous Satellite): This refers to satellites placed in a geosynchronous orbit. While ISRO operates many GSAT satellites, they are typically used for communication and broadcasting purposes.

The Role of NVS-02

The NVS series satellites, including NVS-02, represent the second generation of satellites for India's navigation constellation. These advanced satellites are planned to replace and augment the current satellites in the constellation. Their primary goal is to improve the performance, accuracy, and capabilities of the navigation services offered.

Since the IRNSS system was rebranded as NavIC, and the NVS satellites are designed as upgrades for this navigation service, the NVS-02 is specifically intended to augment the NavIC system.

Why NavIC is the Correct Choice

The NVS-02 satellite is a next-generation satellite built to enhance the existing Indian regional navigation satellite system. This system is currently known as NavIC. While IRNSS is the former name, NavIC is the current operational name and the system that benefits from upgrades like the NVS-02.
