Additionally some refurbishment is required for the rubidium atomic clocks that still have to be launched. For the passive hydrogen masers operational measures are being studied to reduce the risk of failure.China and India use the same SpectraTime-built atomic clocks in their satellite navigation systems. ESA has contacted the Indian Space Research Organisation (ISRO) who initially reported not having experienced similar failures. However, at the end of January 2017, Indian news outlets reported that all three clocks aboard the IRNSS-1A satellite (launched in July 2013 with a 10-year life expectancy) had failed and that a replacement satellite would be launched in the second half of 2017, these atomic clocks were said to be supplied under a four-million-euro deal.
