ISRO's NVS-03 Navigation Satellite Successfully Reaches Geo Synchronous Orbit

The NVS-03 satellite launched by the Indian Space Research Organisation has reached its intended Geo Synchronous Orbit. ISRO shared that four orbit manoeuvres were successfully completed using a cumulative Liquid Apogee Motor engine burn of 6,164 seconds. Following these operations, the satellite reached a Geo Synchronous Orbit of 35,765 kilometres by 36,196 kilometres at an inclination of 29.980 degrees. The spacecraft was initially injected into an orbit of 170.3 kilometres by 38,080 kilometres by a GSLV rocket after lifting off from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, on October 30, 2026. ISRO confirmed that the health of the satellite is currently normal. NVS-03 serves as the third satellite in the next-generation navigation system designed to provide continuous navigation services following the IRNSS series. The payload features an indigenous atomic clock alongside procured clocks, and transmits L1, L5, and S band signals to cover the Indian land mass and an area extending 1,500 kilometres around the geopolitical boundary.

Context

This successful orbit-raising mission follows a previous setback in 2025 when ISRO could not complete orbit manoeuvres for the NVS-02 satellite due to a valve malfunction. Satellites placed in geo synchronous orbits move in sync with the Earth's rotation, which helps them maintain a fixed position relative to the ground for uninterrupted regional navigation and timing services.
