Little popular science: Beidou system is our national strategic industry and plays an important role in national security and improving national competitiveness. Beidou chip is the core component, which will occupy a very important position in aerospace, military industry, future consumer electronics and mobile terminals. It plays an important supporting role in the development of the whole Beidou and even information industries, and will become a growth pole of economic development. Since 2011, the mass application of the state led Beidou industry has gradually entered the consumer electronics fields such as mobile phones, tablet computers and wearables from the fields of transportation, meteorology and fishery. As of October this year, China had launched 20 Beidou satellites, realizing full coverage in the Asia Pacific region. In the field of satellite RF and baseband chips with independent intellectual property rights, in addition to the five Beidou chip manufacturers designated for the pilot in the transportation industry (i.e. two passengers and one danger), a number of enterprises with high-tech content have also emerged, which has made great contributions to the popularization of Beidou application in the country.
