    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.
