India’s autonomous regional navigation satellite system, Navigation with Indian Constellation (NavIC), was created to give users in India and the region that extends roughly 1500 km outside of the Indian landmass—its primary service area—accurate Position, Velocity, and Timing (PVT) services.
On January 29, 2025, at 6:23 a.m., ISRO is preparing to launch the NVS-02 satellite, the second generation of NavIC. It will be the 100th rocket launch for ISRO.
Standard Positioning Service (SPS) and Restricted Service (RS) are the two service categories offered by NavIC. Over the core service area, NavIC SPS offers location accuracy of more than 20 m (2σ) and timing precision of better than 40 ns (2σ).
In order to ensure service continuity, five second-generation NavIC satellites—NVS-01/02/03/04/05—are planned to add improved features to the NavIC base layer constellation. To expand the services, the NVS satellite series also uses L1 band communications.
On May 29, 2023, NVS-01, the first of the second-generation satellites, was launched aboard GSLV-F12. In NVS-01, an indigenous atomic clock was flown for the first time.
Like its predecessor, NVS-01, NVS-02, the second satellite in the NVS series, is set up with a range payload in the C-band and a navigation payload in the L1, L5, and S bands. It has a lift-off mass of 2250 kg and a power handling capacity of about 3 kW when configured on the standard I-2K bus platform. It will take the place of IRNSS-1E at 111.75ºE. NVS-02 makes use of a
With assistance from other satellite-based work centers, the U R Satellite Centre (URSC) conceived, constructed, and integrated the NVS-02 satellite. Following Assembly and Integrated Testing (AIT), the satellite underwent a satellite-level Thermovac test in November and December 2024 to confirm and validate its performance and design in a space simulation. The satellite’s capacity to sustain the dynamic loads expected during launch was confirmed by a dynamic test conducted in December 2024.
On December 27, 2024, a thorough Pre-shipment Review (PSR) of the Satellite’s compliance and performance throughout the many stages of its realization was finished. On January 5, 2025, the satellite was flagged off to India’s launch port, SDSC-SHAR. Now that the satellite has arrived at SHAR, the pre-launch campaign operations are
