    One of India’s four navigation satellites has gone out of service, creating a fresh problem for the NavIC network. ISRO said the satellite IRNSS-1F was effectively lost for core use after its onboard atomic clock failed, a reminder that in satellite navigation, one component can matter as much as the whole spacecraft.

  26. @Ohsin Do not see "attitude control thrusters" mentioned. Mentioned is "The satellite was stabilised in GTO using its gyro wheels".

    May be they try to raise it´s orbit a bit by a "simple" propellant blow down without burning the prop.
