NavIC : India’s Upcoming Second-Generation Navigation Satellite Launch

India is gearing up for an exciting milestone in its space exploration journey as it prepares to send its first second-generation navigation satellite NavIC into orbit. The Indian Space Research Organisation (ISRO) recently announced that the launch is scheduled for May 29, with liftoff expected at 10.42 a.m. from the Sriharikota rocket port in Andhra Pradesh.

GSLV-F12 Launch and NVS-01 Navigation Satellite

The satellite, known as NVS-01, will be carried into space by the Geosynchronous Satellite Launch Vehicle (GSLV-F12) rocket. Weighing in at 2,232 kg, NVS-01 is a crucial component of the Navigation with Indian Constellation (NavIC) services. One notable feature of this satellite is the incorporation of an indigenous atomic clock, a first for India’s navigation satellites.

Navigating with NavIC

NavIC is India’s regional navigation satellite system, comparable to the GPS of the United States, Glonass of Russia, Galileo of Europe, and China’s Beidou. It provides users with accurate positioning and navigation services across various sectors, including transportation, disaster management, and agriculture. The second-generation satellites, of which NVS-01 is the pioneer, aim to improve upon the existing capabilities of NavIC and offer enhanced features.

Unveiling the NVS Series

The NVS series of satellites will sustain and augment the NavIC services. One notable enhancement is the incorporation of L1 band signals, which expands the range of services provided. These advancements signify India’s commitment to continually improving its satellite navigation system to cater to a wide array of applications and user needs.

The Significance of Atomic Clocks

Atomic clocks are vital components of navigation satellites, enabling precise timekeeping and accurate positioning. The Indian space agency had previously utilized imported atomic clocks on its earlier navigation satellites. However, there were reported issues with some clocks not functioning correctly, which impacted the performance of the NavIC system. The inclusion of an indigenous atomic clock on NVS-01 aims to address these concerns and ensure the reliability and accuracy of the satellite’s time and location data.

NavIC and Global Navigation Systems

While NavIC is primarily India’s regional navigation system, it is essential to understand its position among other global navigation systems. GPS, Glonass, Galileo, and Beidou are prominent counterparts, each offering unique features and coverage. By comparing and contrasting NavIC with these systems, we can appreciate the distinct advantages and applications of India’s satellite navigation capabilities.


India’s upcoming launch of the GSLV-F12 carrying the NVS-01 navigation satellite marks a significant milestone in the country’s space exploration journey. The inclusion of an indigenous atomic clock on NVS-01 highlights India’s technological prowess and commitment to advancing its satellite navigation capabilities. With the NVS series and the enhancements they bring to the NavIC system, India is poised to offer improved navigation services to its users across various sectors.
