ISRO launches GSLV-F18 carrying NVS-03 satellite

By · Published by Everything Blog

In short

The mission lifted off at 11:51 pm from the Satish Dhawan Space Centre in Sriharikota, successfully injecting the spacecraft into orbit. It addresses the operational requirements of the ageing NavIC network through targeted replenishments and upgrades. Crucially, the satellite carries an indigenous atomic clock alongside procured units to ensure precise timing capabilities. This ongoing constellation renewal secures independent positioning, navigation, and timing coverage across the nation and its neighbouring areas.

The rocket lifted off from the Satish Dhawan Space Centre in Sriharikota at 11:51 pm. Isro subsequently confirmed that the NVS-03 satellite had been successfully injected into orbit, declaring the mission a success.

The launch is part of India's efforts to replenish and modernise its ageing Navigation with Indian Constellation (NavIC) network, which provides independent navigation services across the country and the surrounding region.

NVS-03 to improve NavIC's navigation capabilities

NVS-03 is equipped with an indigenous atomic clock alongside procured atomic clocks, which are essential for maintaining the precise timing required by satellite-based navigation systems.The satellite also introduces the L1 frequency signal to NavIC, in addition to the existing L5 and S-band signals.

The addition is expected to improve the system's navigation capabilities and expand its compatibility with navigation receivers.

NavIC provides an indigenous alternative to GPS

NavIC is India's independent satellite-based navigation system, developed as an alternative to global navigation networks such as the United States' Global Positioning System (GPS), Russia's GLONASS and China's BeiDou.It is designed to provide positioning, navigation and…
