An Indian navigation satellite launched here on Thursday was declared a failure.

Indian Space Research Organisation (ISRO) Chairman A.S. Kiran Kumar said: “The mission was unsuccessful.”

The 1,425 kg IRNSS-1H satellite – part of Indian satellite navigation system NavIC or originally called Indian Regional Navigation Satellite System (IRNSS) – was carried by Polar Satellite Launch Vehicle (PSLV) rocket’s XL variant on Thursday evening at 7 p.m.

The IRNSS-1H was a replacement for one of the navigation satellites.
