ISRO has published final orbit-manoeuvring details for NVS-03, the Indian navigation satellite launched on October 30, 2026. Its November 4 notice records four completed manoeuvres and a geosynchronous orbit of 35,765 by 36,196 kilometres, with an inclination of 29.98 degrees.
The manoeuvres involved a cumulative liquid apogee motor firing time of 6,164 seconds, according to the agency. It describes the satellite’s health as normal.
This advances the status in our November 2 report, which covered the first orbit-raising burn. ISRO’s October 31 notice gave that burn’s duration as 2,174.8 seconds and the subsequent estimated orbit as 5,477.6 by 37,833.4 kilometres; further manoeuvres were then planned.
NVS-03 is part of the next-generation series for India’s Navigation with Indian Constellation, or NavIC. The government’s November 1 mission factsheet describes intended navigation coverage over India and a region extending 1,500 kilometres beyond its boundary.
The new ISRO notice documents the orbital change but gives no commissioning date or announcement that NVS-03 has entered navigation service.
