Navigation satellite NVS-03 ready for launch, three more to follow: Jitendra Singh

The Story in Brief

The government is working to restore the Indian Regional Navigational Satellite System (NaVIC) and plans to launch four satellites to rebuild the constellation. Space minister Jitendra Singh said in a written reply in Lok Sabha that NVS-03 is ready for launch after corrective measures taken following the NVS-02 anomaly. He added NVS-04 and NVS-05 will follow, and one more satellite is planned thereafter to complete the seven‑satellite NavIC base‑layer constellation. He did not give a timeline for the launches.

The minister noted the 2025 failure of replacement satellite NVS-02 and said corrective actions were incorporated and tested in the CMS-03 satellite; these fixes will be applied to subsequent satellites, including NavIC satellites with bi‑propellant systems. Currently only IRNSS-1B, IRNSS-1L and NVS-01 are providing navigation services. NavIC requires at least four satellites with operational atomic clocks to deliver standalone positioning, and it stopped offering that after the last atomic clock on IRNSS-1F failed in March. First‑generation satellites were launched between 2013 and 2018; NVS-01 reached orbit in 2023 while the 2025 NVS-02 launch failed, delaying NVS-03, NVS-04 and NVS-05.

The Indian Opinion

Some coverage and descriptions of the system’s problems use strong language such as “paralysing”, which can sound alarming to readers. That concern is understandable given the loss of atomic‑clock functionality and the temporary inability of NavIC to provide standalone positioning. At the same time, official remarks describe specific corrective measures tested in CMS‑03 and plans to apply them to the NavIC series. An even‑handed reading recognises both the operational shortfall and the stated technical response, while noting a key uncertainty: no launch dates were provided for the pending satellites. Readers should therefore treat immediate capability claims with caution until launches occur and new clocks are proven in service.
