NVS-02 Mission
1/29/2025
After the NVS-02 launch, refurbishing the Satish Dhawan launch pad is expected to take six to eight weeks before NISAR can launch.
The Satish Dhawan Space Centre launch pad designated for NISAR must first support a GSLV launch of the navigation satellite NVS-02.
A TLE epoch 25051.36290667 for satellite 62850 (NVS-02) lists mean motion 2.16882086 revs per day, inclination 20.8664 degrees, and eccentricity encoded as 0.7400050.
Ground-based optical/radar observers recorded NVS-02 and the GSLV-F15 upper stage over South America on January 29, 2025 at 06:20:29 UTC and over the Indian Ocean recorded between 14:31 and 15:32 UTC on January 31, 2025.
ISRO mission update dated February 2, 2025 states that NVS-02 deployed its solar panels and established communication with the ground station but could not perform orbit raising because valves admitting oxidizer to the thrusters did not open.
The 18 SPCS object record for 2025-020A (NVS-02) has epoch 2025-01-29T18:00:01.485216 and inclination 20.7548 degrees.
An initial cataloged orbit for NVS-02 was approximately 161 km by 37,602 km with inclination about 20.7 degrees (geotransfer orbit).
ISRO described NVS-02 as currently in an elliptical orbit and noted alternate mission strategies for utilising the satellite in that orbit were being evaluated as of February 2, 2025.
India's NVS-02 navigation satellite (IRNSS-1K) was launched on GSLV flight F15 from Satish Dhawan Space Centre at 00:53 UTC on January 29, 2025.
The GSLV-F15 mission in January 2025 was a partial success in which the navigation satellite NVS-02 could not be maneuvered into its designated geostationary orbit.
The NVS-02 mission is expected to launch from the Satish Dhawan Space Centre around mid-January 2025.
