Regarded as one of India’s four navigation satellites has failed, a setback for the NAVIC network. Satellite tv for pc IRNSS-1F used to be misplaced after its atomic clock stopped functioning.
Most appealing three satellites — IRNSS-1B, IRNSS-1L and NVS-01 — remain operational for providng positioning, navigation and timing (PNT) products and companies across the Indian subcontinent. The shortcoming of one degrades impart products and companies equipped by the NavIC system, a regional navigation satellite tv for pc system designed to enhance world systems (an SBAS).
“IRNSS-1F satellite tv for pc launched in March 2016 has accomplished its accomplish mission lifestyles of 10 years on Tenth March 2026,” the Indian Space Learn Organisation (ISRO) announced. “On thirteenth March 2026, [the] procured on-board atomic clock stopped functioning. However, the satellite tv for pc will proceed to operate in-orbit for various societal applications to scheme one-methodology broadcast messaging products and companies.”
Since July 2013, the Indian Space Learn Group (ISRO) has launched 11 satellites. Since then, six like failed, largely attributable to defective imported atomic clocks in the preliminary part and, in some unique cases, attributable to orbital issues.
In 2025, the government acknowledged that finest four of the 11 satellites deployed for the NavIC system had been entirely operational for PNT products and companies, whereas the closing spacecraft had been being utilized in a restricted or sub-optimal skill.
