ISRO's 100th Launch: NVS-02 Satellite

Context

The Indian Space Research Organisation (ISRO) is poised to make history with its 100th rocket launch (GSLV-F15 mission), marking a significant milestone in India's space journey. The GSLV-F15 rocket with indigenous cryogenic stage will place NVS-02 satellite in a Geosynchronous Transfer Orbit.

Key Features of the NVS-02 Satellite:

Weight: 2,250 kg
NVS-02 satellite is the second of five second-generation satellites designed to enhance India’s Indian Regional Navigation Satellite System (IRNSS), also known as NavIC.
NVS-02 is part of a new generation of satellites designed to replace older ones in the Indian navigation constellation.
- NVS or Navigation Satellite is part of the Navigation with Indian Constellation (NavIC) - India's version of a Global Navigation Satellite Systems (GNSS) - similar to the Global Positioning System (GPS) often used worldwide.
Lifespan: These second-generation satellites have a longer lifespan of 12 years compared to older satellites, which were designed for 10 years.
Atomic Clocks: NVS-02 is equipped with indigenously developed, more accurate atomic clocks, improving the satellite's navigation precision.
L1 Frequency: The satellites use the L1 frequency, commonly used by the US GPS, which will help expand the system’s use in smaller devices like fitness trackers and smartphones.
Rocket: The GSLV-F15 rocket will carry the NVS-02 satellite into a Geostationary Transfer Orbit (GTO), which has a perigee (lowest point) of 170 km and an apogee (highest point) of 36,577 km.

IRNSS (NavIC) System:

IRNSS, or Navigation with Indian Constellation (NavIC), is a 7-satellite system that provides navigation and timing services across India and up to 1,500 km in its neighborhood.
The first satellite, IRNSS-1A, was launched in 2013.
Replacements: The constellation has faced challenges, including issues with atomic clocks on some satellites, which required replacements before their mission life ended.
Issues Faced in the Past: In the past, some satellites had issues with their atomic clocks, causing a delay in the expected timeline of replacements.
A satellite, IRNSS-1H, failed to reach orbit due to a malfunctioning heat shield during launch.
