A state-owned engineering firm has successfully used China’s homegrown Beidou navigation satellites to help collect upper-atmosphere weather data, the South China Morning Post reported Tuesday. This is another step toward ending the country’s dependence on GPS (global positioning system) technology controlled by the United States. The Beidou system developed by Beijing Changfeng Microelectronics Technology helps pinpoint the location of radio equipment on weather balloons, allowing accurate meteorological analysis without relying on foreign technology, the report said. The breakthrough will benefit civilian and military users but the People’s Liberation Army will remain dependent on GPS to provide accurate navigation data for its weapons systems for the time being, the report said.
