 China has successfully launched a hyperspectral imaging satellite 'Gaofen-5' for comprehensive observation of the atmosphere, including air pollution which is one of the country's major problems. The Gaofen-5 satellite was launched off the back of a Long March 4C rocket from the Taiyuan Satellite Launch Center. It was the 274th flight mission by a Long March carrier rocket. It has a designed life of eight years. Gaofen-5 is the first China-developed satellite that can monitor air pollution. It can dynamically reflect the state of air pollution in China through the monitoring of air pollutants, greenhouse gases, and aerosols. The Gaofen project began in 2010. |

 The Indian Space Research Organization has developed an atomic clock to be used in navigation satellites. It is supposed to measure precise location data. Once it successfully clears all tests, the desi atomic clock will be used in an experimental navigation satellite to test its accuracy and durability in space. At present, ISRO imports atomic clocks from European aerospace manufacturer Astrium (EAMA) for its navigation satellites. With the development of indigenous atomic clocks, the space agency sure gets a mark of technological advancement. |

 The Indian Space Research Organisation launched the Indian Regional Navigation Satellite System-1I, the eighth such satellite to be a part of a constellation. It was launched from the first launch pad at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. IRNSS-1I is expected to replace IRNSS-1A, the first of the seven navigation satellites that was rendered ineffective after its three rubidium atomic clocks failed. The seven satellites are part of the NavIC navigation satellite constellation. |
