The Indian Space Research Organisation (ISRO) successfully launched the NVS-02 satellite, part of the Navigation with Indian Constellation (NavIC) system, marking its 100th satellite launch from Sriharikota. This significant milestone strengthens India’s indigenous navigation capabilities and advances its space technology ambitions.

Key Points

ISRO launched the NVS-02 satellite aboard GSLV-F15 from Sriharikota on Wednesday morning.

This marks ISRO’s 100th satellite launch from the Satish Dhawan Space Centre (SDSC).

NVS-02 is part of the NavIC system, enhancing India’s regional navigation services.

The satellite weighs nearly 2,000 kg and was successfully placed in a Geosynchronous Transfer Orbit.

NavIC offers Standard Positioning Service (SPS) and Restricted Service (RS) for precise location tracking.

A new spaceport is under development in Kulasekarapattinam, expected to be operational within two years.

ISRO Chairman Dr. V. Narayanan confirmed the success of the mission, marking his first major launch since taking over.

Mission Overview

The GSLV-F15 rocket lifted off from Sriharikota’s second launch pad at 6:23 AM IST, carrying the NVS-02 satellite. The launch vehicle successfully deployed the satellite into a Geosynchronous Transfer Orbit about 19 minutes after takeoff. ISRO Chairman Dr. V. Narayanan confirmed the mission’s success, making this the first ISRO launch of 2025.

NVS-02 and NavIC: India’s Advanced Navigation System

NVS-02 is the second satellite in the NVS series, designed to improve NavIC, India’s regional navigation system. The satellite offers:

Standard Positioning Service (SPS): Open for civilian use, with an accuracy better than 20 meters.

Restricted Service (RS): Secure navigation for military and strategic applications.

Equipped with advanced payloads in the L1, L5, and S bands, along with a C-band ranging payload, NVS-02 enhances India’s navigation capabilities for:

Terrestrial, aerial, and maritime navigation

Precision agriculture and fleet management

Emergency response and geodetic surveying

Location-based services in mobile devices

ISRO’s Historic 100th Launch from Sriharikota

Since its first satellite launch in 1979, ISRO has achieved 100 successful launches from Sriharikota across various missions. These include:

PSLV: 62 launches

GSLV: 16 launches

LVM3: 7 launches

ASLV & SLV: 4 each

SSLV: 3 launches

Additionally, 537 launches have taken place at the Sounding Rocket Complex in Sriharikota since 1971.

New Spaceport at Kulasekarapattinam

ISRO is developing a new spaceport dedicated to small satellite launches in Kulasekarapattinam, Tamil Nadu. Unlike Sriharikota, this location allows rockets to head directly south, avoiding fuel-consuming detours around Sri Lanka. The spaceport is expected to be operational within two years.

Conclusion

The launch of NVS-02 aboard GSLV-F15 marks another major achievement for ISRO, enhancing India’s independent satellite navigation system and setting the stage for future advancements. With plans for a third launch pad in Sriharikota and a new spaceport in Tamil Nadu, India is rapidly expanding its space capabilities, reinforcing its position as a global leader in space exploration.
