Why in News?

ISRO successfully conducted its 100th launch from the Satish Dhawan Space Centre in Sriharikota.

The launch vehicle GSLV-F15 placed the NVS-02 satellite into orbit.

The mission marks a significant milestone in India’s space program.

Key Highlights of the Launch:

GSLV-F15, equipped with an indigenous cryogenic stage, lifted off at 6.23 a.m.

NVS-02 is the second satellite in the NVS series under the Navigation with Indian Constellation (NavIC).

The mission is a testament to India's growing capabilities in space technology.

Importance of the NavIC System:

NavIC is India's independent regional navigation satellite system.

It provides accurate Position, Velocity, and Timing (PVT) services within India and a 1,500 km range beyond the Indian landmass.

Offers two types of services: Standard Positioning Service (SPS) and Restricted Service (RS).

NavIC-based applications support strategic uses, shipping vessel tracking, time synchronization, train tracking, and safety alert dissemination.

Technological Advancements:

Introduction of indigenous atomic clocks in the NVS series, a major milestone in “Make in India.”

Strengthens India’s autonomy in satellite navigation.

Enhances navigation accuracy for both civilian and military applications.

Future Roadmap:

ISRO plans to launch five second-generation NavIC satellites to enhance the NavIC constellation.

The first second-generation satellite, NVS-01, was launched in May 2023.

The continued deployment of the NVS series will further establish NavIC as a robust alternative to global navigation systems.

ISRO’s Milestones and Achievements:

• Over 100 launches conducted, placing 548 satellites in orbit.
• Total payload lifted: 120 tonnes, including 23 tonnes for 433 foreign satellites.
• The launch signifies ISRO’s growing role in global space exploration and satellite technology.

Strategic and Economic Implications:

• Strengthens India’s self-reliance in navigation and positioning services.
• Reduces dependency on foreign satellite navigation systems like GPS.
• Enhances India’s global standing in space technology and satellite-based applications.
• Boosts commercial satellite launch capabilities, attracting global partnerships.

Conclusion: ISRO’s 100th launch is a historic event that underscores India’s progress in space technology. The deployment of NavIC satellites strengthens India's satellite navigation capabilities and reinforces its position as a global space power. The mission aligns with national interests, scientific advancements, and economic growth, paving the way for further innovation in satellite technology.
