Why in News?

GSLV-F15 NVS-02 mission is the 100^th launch from the Satish Dhawan Space Centre in Sriharikota, scheduled for January 29.

GSLV-F15 NVS-02 – Geosynchronous Satellite Launch Vehicle (GSLV)- F15/ Navigation with Indian Constellation-2 Satellite (NVS-2).
GSLV-F15 – 17^th flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV).
- 11^th flight with – Indigenous Cryo stage.
- 8^th operational flight with – Indigenous Cryogenic stage.
Payload – Its fairing is a metallic version with a diameter of 3.4 meters.
It will place NVS-02 satellite into a Geosynchronous Transfer Orbit (GTO).

NVS-02 satellite – It is the 2^nd satellite in the NVS series.
Navigation with Indian Constellation (NavIC) – NVS-02 satellite is part of NavIC.
It is India’s independent regional navigation satellite system designed to provide accurate Position, Velocity and Timing (PVT) service to users in India.
It extends to region of about 1500 km beyond Indian land mass.
U.R. Satellite Centre (URSC) – NVS-02 was designed, developed and integrated at the U.R. Satellite Centre (URSC) with the support of other satellite-based work centres.
Navigation Payloads – It operates in L1, L5, and S bands and employs Tri-band antenna.
Rubidium Atomic Frequency Standard (RAFS) – Is the main component of the navigation payload.
RAFS is an atomic clock which acts as a stable frequency reference for the navigation payload.
Ranging Payloads – It consists of C-band (CxC) transponder used for 2-way Code Division Multiple Access (CDMA) ranging to facilitate precise orbit determination.

Lift off mass – 2,250 kg.
Power handling capability – Approximately 3 kW.
Usage – A combination of indigenous and procured atomic clocks for precise time estimation.
